A/C resistor???
Hi All,
Was looking through some old receipts from the dealer service records I have in the porsche folder. I noticed that the dealer left a recommendation for me to get the A/C resistor replaced at a cost of $455 installed.
I have a few questions??
1.) What does the A/C resistor do?
2.) Is this just a relay or switch that I can replace in the fuse panel?
3.) what would happen to let someone know that the A/C resistor is not working properly?
4.) what is the worst thing that could happen if it isn't replaced?
I tried to do a search on this but after reading a few posts I think I am even more confused than when I started.
Thanks,
Ryan

1. The AC resistor is what gives your AC fan its lower speed operation.
2. The resistor is mounted atop the AC cooler in the left front fender. It is DIY'able, but you will get your hands dirty.
3. Not easy to tell in normal usage if it is not working. I performed a test to verify that my AC resistor was not working.
4. The fan speed is driven by a thermostat or temperature sensor. When the low speed fan does not work, the AC
gets hotter before the high speed fan kicks in. Your AC parts get hotter for a longer period of time and they are not likely to last as long.

I'll get this replaced before I start using the A/C this year.
I wasn't sure how important this was to normal operation of the car. Of course the dealership fails to answer these questions and made me feel as if I didn't replace it the world would end.
I'll have my independent mechanic do this at the annual service this year.

You should do the oil cooler resistor at the same time. It is essentially the same part and if the A/C one is bad then the oil cooler is likely just as corroded. When I took mine off with 50k it came off in two pieces. FYI it involves removing the bumper I believe.

I would also do a search - there are likely threads out there covering as well

I did mine a couple months ago, no need to remove the whole bumper. Took about an hour each side, parts are about $80 to $90 per resistor for OE. Or you can build a much better resistor that is cheaper and will last longer but is not OE. Follow this link for that DIY.

There is a good DIY to fabricate you own resistor that will have a much longer service life and replaces the fusable link with a temperature resetting switch.https://rennlist.com/forums/993-foru...llast+resistor

Does anyone know if the A/C resistor and Oil cooler resistor are the same part??
The ToreB site lists part number 993 616 521 01, but I wasn't sure if that is the same for both A/C and oil cooler resistors.
If anyone knows that would be a huge help!
Thanks,
Ryan

Same part. Just did both on the 97 and neither of the old ones were pretty. As others have said, do them both.
