Common A/C problems

Hi All,

Can anyone pls give me an idea of the common probs with the A/C on the 993's I understand the ballist resistor is the most common followed by a re-gas every year is this correct? Is it best to run the A/C all the year round on normal like most climate controlled cars.

Thanks

yep, that is my understanding.. although from experience it is always good to run the a/c at the coldest and hottest settings a few times a year in order to give it a good 'working'

The best way to keep the a/c in top condition is to run it for a short period at least once a month so that it keeps all the seals from drying out. Trouble is you can do that as much as you like but if the previous owners didn't then the a/c may always be bad unless you spend money on it (and I don't think it is cheap). Once the seals have deteriorated then the gas leaks out (either slowly or rapidly). Regular re-gassing will help but only last until it has leaked out again (which may be less than a year).

PS I wouldn't exactly call the 993 climate controlled. The system is a lot cruder than that IMHO.

Perhaps I am being too hard on it but the fact the system does not automatically vary the fan speed as part of its control makes it a bit on/off and therefore crude to me. Or maybe it's just crap in my car [&:]

A couple of years ago I had to replace the A/C condenser and drier then regas it again. I also changed the condenser fan slow speed resistor at the same time as I noticed it was cracked when working on the car. It cost about £500 to sort the A/C out, but its been ok ever since.

Not sure the 997 brigade would be too chuffed with this description of the comparison car [:D]

From what I'm reading, the 997 brigade won't be too chuffed about the Cayman either. To quote this months GTPP, "Cancel that 911!" so maybe having state of the art climate control will be the 997's big selling point! [;)]

From my experience the air-con on the 993 is a bit stone age, although a re-gas with conditioner in it improved matters no end. The major problem seems to be loss of coolant due to the low speed resistor packing up, or so my local air-con specialist considers. Otherwise, he finds the system fairly bombproof. Perhaps in some cases, less is most definitely more!

Now that's the problem with you lot in the south of the north - you all try to adopt a sense of humour. Just remember, Peter Kay comes from the proper north, so end of subject - (before I get myself hung!!!!) [:D][:D][:D]

But you are right and I should have explained a little better, so one point to you [;)] What he told me was basically as you said - temp too high and too much pressure causes a loss. Apparently though, our beloved marque isn't the only one to suffer with the problem of low speed fans packing up. He'd had one customer that had been to another 'specialist' and they were replacing lines, condenser and other bits because they kept losing coolant. He'd ended up with a big bill and tried my bloke. Quick fan diagnosis and the job was sorted! Just goes to show how some enthusiastic amateurs can miss the mark!

they assumed Targa drivers are more laid back, so have allowed us to change things [&:][&:][&:][&:][&:]

HOW I miss climate control [:eek:] at least the A/C works....... now and again !
 
Ian,

The system is closed loop so technically it is Climate Control rather than just AC. However, to use your words "it is crap" and you end up having to adjust it constantly.

Sounds like your sensor fan is kaput - can you hear it after you switch off ? Just behind the CCU in the dash ....

Forgive the ignorance but should you be able to hear that fan once you turned everything off and are leaving the car??? Mine does & I've always wondered if it should.

I've also wondered if this fan has been the cause for the alarm to occasionally go off (just in hot weather) - the ultrasonic sensors being the trigger code??

Cheers
Stan
