Possible ignition switch issue

[Gilles]

GSY,

A few years ago the same symptoms started on my '07 Cayman S, sometimes no juice to the starter after turning the key but everything else was working ok.

The fact that it was an intermittent issue made it harder to diagnose, I installed a new switch and didn't cure the symptoms (even removed the starter and got it checked for it's proper operation)..

However, by pure coincidence we found the culprit... it ended being the Positive Cable that goes from the battery (through the firewall) to a some type of 'power distribution box' that is located inside the cabin behind the glove box.

The positive cable connects into this box via an unusual "friction connector" you will see what I mean after you remove the cable, on my car, I removed the cable, clean it properly and reinstall it with some dielectric grease, and the issue never showed up again.

However, it drove me nuts since the failure was intermittent..

Good luck!

Problem just started without warning last Friday. Left for a doctor's appointment and noticed my AC wasn't working. Got to the parking garage and noticed my lights weren't working either. Fuses?. I took the key out and the steering wheel lock wasn't engaging and the chime was sounding. Couldn't lock with the fob. Key in door to lock and one beep. When I left, I turned the key slightly left and stuff was working.
Got on the Forum and yup - the famous ignition switch issue. Ordered Meyle (thanks posters for suggestion) from Amazon $26. Gonna install it tomorrow.

Pomona. That's "up the street from me". I know who I'm scouting when the gremilins strike my car.

Used Pedro's instructions, and I don't doubt his expertise, but I couldn't get enough leverage to loosen the screws. The left duct was hindering me, so I modified my approach:

Removed left vent ass'y


Removed left duct.



Plenty of room to get my hand in there, plus one can use both hands from above and below. Maybe the difficulty is I'm left handed.

btw - as far as going under dashboards, back in the '60's we used to service car radios, so I'm no stranger to that, but not as agile as i used to be

How long did that take you? Thanks!

Well, I wasted maybe a half hour or so in the initial attempt, but removing the vent is essentially the procedure for replacing the light switch, so using this method, less than a half hour. I'll need to get in there again because I couldn't get the duct back on the left side, so I'm thinking fit the left and lower left duct together before screwing the left duct on. I learned so much doing the suspension; you spend extra time on one side and the other goes smoother

I need to do this and I know I would not be able to do going from the underside, bad back and stiff as a board. Going thru the vent looks to be much easier. Did the vent go back in nice?
