Air con

[itskenallen]

Just wondering if anyone has had their air con refilled or any other work done.

Mine doesn't seem to get cold at all when set to cold and was wondering how I'd tell if it needs a refill or could it be something else?

TIA

First... is your compressor engaging?

Next, see if you can get a set of A/C gauges to attach to the low/high side ports and record the pressures. It could be that the refrigerant is low.

But A/C issues can be many different things, best to start with the simple steps first.

Servicing A/c is quite complicated and requires special equipment.It is easy to make the problem worse. So unless you want to climb a steep learning curve and buy the equipment it is usually better to use a specialist. Meanwhile you could just get a recharge kit and try that

The AC on my Boxster wasn't working so I did some research. It wasn't that hard to repair.

It seems Boxsters tend to suffer from damaged condensers (these are the small radiators tucked in the front bumper - one for each side). An encounter with high speed debris while driving can cause a puncture with the resultant loss of refrigerant).

Have a look at the condensers first. You can have a quick look at them with a strong flashlight, but the damage might be further back and only visible once the front bumper and ducting is removed. My damage was hard to see so I moved on to the next step.

There is 134A refrigerant that comes with dye. The idea is you add some in while the compressor is running , and then look around the AC components/connections with a UV light looking for where the leak is.

I couldn't get my compressor to turn on with the dashboard controls. When I pulled the engine covers off I saw that someone had disconnected the single wire connecting the compressor to the wiring harness for the car. I reattached it and still no joy.

The compressor will not come on unless there is sufficient refrigerant in the system. I ran a wire directly from the compressor to a car battery and it worked. Caution: Don't run it for too long if there is no refrigerant in the system as you might have insufficient lubricating oil in the compressor to lubricate it. I took my chances.

I added the refrigerant dye mixture into the running system and almost immediately I could hear a loud sound of air escaping. I turned off the car and tracked the leading air to both condensers. The UV light confirmed the condensers were toast.

I ordered two new condensers, a new dryer (it's a must), some o-rings, refrigerant, a food scale (for weighing how much refrigerant to add, an evacuation tool, and the AC recharge tool ($50 at Harbor Freight).

I took my time, watched some videos, and by the end of the weekend I was sitting in a nice cool Boxster.

Good Luck!

Some great info there guys thanks. I guess the easiest place to start is to ad a bit of refrigerant and see from there.

If the R134a is gone, or the R134a loop is opened they system will need to be repaired and then drawn to vacuum before refilling with R134a for the system to operate. Refilling the R134a with air already in the system will prevent proper operation.
