A/C temperature sensor


Recommended Posts

Well.. I posted this thread a while back. Here is the sympton

- Start the car and turn on the A/C.. got nice cold air.. turn off the car and wait for 10 mins.. then drive the car again

- Nothing but hot air. A/C won't work (I suspected the sensor fault, if Loren can still remember it)

Burlingame Rector charged me over $1300 and trashed my a/c lines and didn't even know or not willing to fix it.. So I have to find a local a/c shop and spent $700 to restore what Rector trashed. But the hot air still blowing.

So I found Bob in Sunnyvale to fix my tranny, I also asked Bob to take a look at it. Well, Bob said, there was one air sensor missing (pass side air sensor). and that was it..

After $2000, we fixed it for a bit more than $100.

I can't say anything about Porsche dealers in SF bay areas. Not recommended. Find a good specialty shop to take care of your baby.

Hmmmm.....

Missing/open OAT would most typically mean no A/C operation at all. Open OAT would indicate VERY cold, sub-freezing, OAT and very few systems, if any, would run the A/C compressor in that circumstance.

Your initial problem sounded somewhat normal to me. Engine water jackets oftentimes overheat a few minutes after engine shutdown. Some manufacturers allow the electric cooling fans to run in this mode but Porsche does not. So when you restart the car within ten minutes it may very well be that the water jacket is overtemp and that will definitely lock out the A/C.

Yeah.. That's the Bob.. Don't know why he lost all his hairs. Too close to the turbo engine heat, I think.

Note: Not the monster garage. Didn't see Sandra Bullock in his shop.

Interesting comments, wwest. I think that's what it was. The car actually thought I was freezing.
