Electrical problems / car won't start after rain downpour

[kcpstudio]

OK.... and so it begins.

I just purchased a 1997 Porsche Boxster and had it about 2 months now. Last couple days we had severe downpours. Right after purchasing the car, I had a brand new OEM top put on by the dealer's top guy.

Two nights ago we had an extreme rain downpour and all the windows were up. The next day, I came out and found my passenger window all the way down and the driver's side window erratically moving up and down a couple inches... as if I was trying to open the door. The interior was soaked and I had 1 1/2 inches of water in the driver's side floor pan.

When I opened the drivers door, the window stopped moving. When I closed it again, it would start up again. Anyway, my neighbor owns a carpet cleaning business and he came over and vacuumed the floors and removed all the water.

The car will not start but the dash lights come on. The headlights all work. The AC unit powers on. The radio powers on. The windows do not work when I try to push either of the switches. The "door lock" switch on the dash is lit but the door locks will not work. The red LEDs on the dash board for the alarm are on steady and don't flash. The horn works. BUT, when I turn the ignition key, I get nothing.

I went under the front hood to look at the battery and found water filled up the pan on the driver's side of the battery. The drain tube was clogged and I cleaned it out. The water all drained out. I'm going to guess that enough water kept filling there that it leaked badly into the cabin through a small opening in the firewall where a cable runs... right near the stearing shaft.

MY GUESS: the immobilizer under the driver seat got wet? If that's where its located. BUT, what caused the windows to go down and the one to act irratically? I disconnected the battery and reconnected. After about an hour, the windows went back up on their own. Then, as I opened the driver's door, the window went down a few inches but wouldn't go back up. Everything else is still the same. So, I disconnected the battery all together until I can figure this out. If water came in through the little hole in the firewall because of the drain tube being clogged, would all that water in the floor pan cause the windows to come down and act like this? Then, with the windows down and all the rain, my leather seats are like a sponge.

Please, if any of you have had a similar isse, please list what ultimately went wrong and needed to be fixed. I can't afford a dealer right now with my current situation with lack of work for my business. I'm not getting rid of the car... I love the car. If I only knew about that dame drain tube. I had the car inspected before purchasing and they said it was a great car for the money.

Thanks everyone.

I forgot to mention.... the key remote doesn't work as well to unlock the doors or the rear trunk lid.

You need to check all the drain holes for the vehicle. As you already found one blocked front hole you need to check the other front one also. In the rear there are two drain holes located underneath where the convertible top folds down. These drain down just in front of the rear wheels. You need to follow the procedure to place the top in the service position and the drains are located one in each corner. Also check the rubber tub has no tears in it which also allow water entry to the cabin.
The module under the left seat is the main computer controlling most of the vehicle. The water will have shorted out the electrics, thereby causing the erratic widow operation.

kenny first off can you get the car inside a garage and give it the chance to dry out. disconnect the battery (turn to 1st click before disconnecting to stop the alarm going off) and dry it out with the doors and lids open

some moisture in the module may be the cause of the windows having a fit. was there any issue with any electrics prior ?

as you know, when you release the hood handle the windows drop, moisure seems to be getting in somewhere

was the roof tested for leaks after being fitted ?

you also may want to look at leather creme for the seats re: watermarks on the leather. maybe beg/steal/borrow a de-humidifier ?

good luck and let us know your progress/thoughts/findings...

[kcpstudio]

The roof was tested after install and the dealer said I was good to which brings up a question.....

Why didn't they check the drain holes... especially if I paid them to replace my top to keep my interior dry. Lol I mean, I'm getting way better information about my car from a great (and I mean way valuable great) website right here. I would think they would check that.

As for electronics? No issues prior... at least while I owned the car. I've been reading all kinds of info here since I joined and have purchased the Bentley manual and dealer service manual and parts manual on disc. The Top was the first thing to replace. The only thing besides that that needed to be fixed was my "Boxster" emblem on the back trunk was cracked. That's it and I got a great car. Now.... lol....

So, we've been having some good sun these last couple days so I've been leaving the windows open. I was going to pull the seats and carpet out and go from there. I don't have a garage and don't know anyone that does.

Here's an important question.... how can I get the windows up before I get the damage fixed? We have some more rain coming.

Thanks to all you guys for the help. Especially while I get up to speed with the car.

I park outside too. Only have a one car garage and it is filled with a project car. The best advice I can give you is to get a "good" car cover if you park outside. You can get one online for around $150-160, maybe cheaper it you search more. I got a Covercraft one and it is great.

They most likely just ran a hose over it for a few minutes or ran through a car wash, no visible water inside. Lets call it good.

Your frienly neighborhood Porsche tech is only as good as the man is. Some techs go that extra mile some do not. It looks like you got the latter. Remember alot of people these days don't do the best work they can but instesd just skate along and collect the paycheck. The one time that I had a dealership work on my car I told them that I only wanted one tech to touch my car. I did not care how long it took him to fix it but I wanted only one person responsable for my car. When I talked with that tech a couple days after he had been working on my car I found out that he was a rat rod V-8 guy who hated VW's. I asked him why he worked on them and he said "Because the pay is good."

Thats because we are all sick...with porsche fever, one of the symptons being permagrin.

Glad to hear it got paid for by insurance. Way to go GEICO.

Hello all, my first post. Thanks for a great site.

I bought my Boxster at the begining of September just before my holidays. took 3 weeks off work and got 1.5 days of sunshine that's it.

My car got soaked for 2 days and my heater fan stopped working everything else is fine, after reading the other posts I found that all my drain holes were plugged so I cleaned them all put a little electric heater with fan and have dried out my car.

I bought a shower curtain to cover the roof and engine access cover which I hold down with magnets and then put my car cover on top as it does not seem to be 100% waterproof as the add on Ebay claimed it was...

Anyhow I checked all my fuses and still the heater/defrost motor will not come on.

My AC used to work fine but when I press on the AC button now nothing happens... I ordered a manual and am awaiting delivery.

Any suggestions would be welcomed.

Thanks.
TC

Here's a question.... I have full coverage on my Geico auto policy with 0 deductible for my comprehensive. I'm wondering if damage due to heavy rain is covered.

Seems like a telephone call to GEICO is in order.

[kcpstudio]

Called the little grren guy up and the claims rep said that it would be covered under flood in my comprehensive policy. Yeah

BUT, I'll still post everything that happens and let you all know what the dealer replaces etc. This way anyone who runs into this and the insurance doesn't cover it, at least has some information to help.

[kcpstudio]

Got my car back today from the shop.... finally. Well, $3,600 in damage. Insurance took care of everything... thank GOD. Basically, the box under the drivers seat got flooded and shorted out. That then killed both door lock solenoids, horn, and convertible top switch where the latch locks. Because I didn't have my key codes, they replaced all the key remotes. I'm just glad I still have some good weather left to enjoy the car before it gets put away.

Hi everyone!

So, unfortunately I’ve experienced this same problem twice within six months. I’ve taken it to Porsche to get repaired again, but now they’ve doubled the repair cost. I reached out to Porsche corporate about this issue since I recently paid $4000 in Aug 2017 to get it fixed, and now it’s Mar 2018 with the same issue at $8000.

Sadly, they stated that it isn’t apart of their 12 month warranty nor is it there problem. Thankfully , Ive kept all my service records because telling me that the water damage was my fault because I didn’t have it garaged it’s insane. The car only is worth about $20,000, but they expect me to kept filing claims because of their crappy design.

With that being said, I’m started chatting it up with an attorney over this matter and I will be filing a lawsuit with this company. If anyone whose experienced this issue, or know someone who has, would like to join this lawsuit, feel free to forward your information to me. I think we all deserve answers from Porsche and better customer service when we’re paying thousands of dollars for their vehicles.

No. I don't understand your frustration. Water in the passenger cabin is caused by clogged drains. It's your responsibility to make sure the drains are clean. Didn't you learn anything the first time?

Your complaint is akin to running an engine without oil in it, then getting mad when it seizes.

I live in SoCal. My car is covered all the time. Driven only on weekends. Not driven in rainy or inclement weather.

Once I found this forum, and stumbled upon a thread about cleaning drains (and the importance of), I was on that task quicker than stink on ****************. The ramifications of unintentional water damage was enough to inspire me to spend 30 minutes clearing drains.

Sue Porsche. lol. smmfh

No disrespect intended, but suing Porsche is probably not going to accomplish anything other than to make you MORE frustrated. The reality is, for all anyone knows, you left the top down and it rained. If it ever gets to court I'm sure Porsche will bring that up...

Your insurance company may pay for the repair - that depends on what kind of coverage you have. Might also depend on whether you filed a claim the first time this happened.

But, the first thing you need to know is HOW the water is getting into your car. Are the drains clogged? This can happen if you leave your car outside - leaves and other debris can clog them. Owning a convertible brings with it certain responsibilities - among those are ensuring that you maintain (clean out) the drains, regularly check all convertible top seals, etc. Did you have any work done on the doors? If the door water seals weren't properly re-installed that could cause water to get into the car.

You found these forums and that's a wonderful thing. There is a lot of great information here. Just use the search function and search for information on "water", "immobilizer", "leaks", etc. You'll find that there are much less expensive (and better) ways to get your car repaired that taking it to the dealer. There are at least 2 places that can repair your immobilizer. There's also a waterproof case that can be installed to protect the immobilizer from future water damage.

I'm really sorry that you are going through this, but suing Porsche is probably going to be like chasing windmills. If you go that route, I wish you luck.

When you pay someone to fix a problem and they don't it becomes there problem I would be frustrated just like you. They should have cleaned your drains for sure with that amount of money you spent there.

[maytag]

Oh y'all are killin' me! Haha!
Seriously, you're going to sue Porsche? Hehe. I'd suggest that if this idea belongs to your attorney, you may want to just write him a check now and walk away. It'll be much less aggravating for you, and net the same result. And then he can go back to chasing ambulances.

More seriously: How old is your car? How many miles? The saying goes: Fool me once, shame on you. Fool me twice, shame on me. You have no one to blame for this but yourself, frankly.

Expensive lesson, yet you still seem to have not learned it. Hehe.

I left my Boxster parked in my driveway while I was traveling for work …you know where this story is going. Correct: I returned to find the cabin full of water.
I've cleaned up cabin, cleared the drains, and dried out the Alarm module.

Once back together the car functions correctly …with one exception: the doors won’t lock.

- the door lock button on the dash: the LED is on but the button does nothing
- pressing the key remote: I can hear mechanical noise inside the driver’s door but the door is remains unlocked
- locking the car with the key, manually: the drivers door will lock but the passenger door is not locked

Using the Durametric I have no Fault Codes.

Any ideas of what my problem might be?

my car: 2003 Boxster, manual, <60K miles
Here’s the status of each Alarm I32 sensor (with the driver’s door open)
