The mechanic said he was 99.9% sure it was a
control module, so Steve hunted around every wrecker in the area, without
success, so we purchased a new one at $196.00. It was put in, but turned
out to not be the problem. The problem was a $20.00 temperature sensor......but
VW will not take back the control module because it's electronic. So now we're
stuck with it!!!! Typical eh???
In the end, we have wonderful, cold
air!!!!
Love K.

OK all
you mechanically-minded thinkers, I have a puzzler of the week for you all,
before I fork out hundreds of $$$ to the VW mechanics. I have a 1996
VW Jetta with powerlocks and anti-theft devices, 4-door, 5 speed with
air. The air conditioning system had been blowing only regular
temperature air, so before we paid an a/c specialist, we took the problem to
Dave G. (I hope I have all the details Dave, so correct me if I'm
wrong.) He and Steve filled and checked the compresser which seemed to work
as long as they had the compresser being charged.
What
did they charge it with? Just compressed air?
When the charge was removed, the cool air stopped and they came
to the conclusion that it was a problem with the wiring. On Monday we
took the car to the dealer that we bought the car from and they were to have
the mechanic check it out. Yesterday the mechanic called and said that he
didn't have the equipment to check air conditioning, but would have it
checked by a local mechanic who has the equipment. He called me back and
said that the other garage refused to touch it because they didn't know what
was added to the compresser, and he wouldn't go any further until that was
determined.
Probably the reason he's saying this is
because the refrigerant normally used has an oil added, and this misted oil
circulates through the cooling system, lubricating the compressor. If the
system is empty and is then charged with compressed air and run, the
compressor runs without any lubrication. If it's run that way for long enough,
the compressor will be damaged.
He
wouldn't consider checking the wiring, because he thinks it's a problem with
the compresser. When I went to get the car, the battery was totally
dead and they had to charge it up again, telling me to take it to a licensed
a/c dealer or VW mechanic. When I left the lot, the a/c came on and
worked beautifully, but the re-circulation button would not turn
off.
No idea about that.
Today, the car is dead again, but the hazard lights stayed on, whether a key
was in the ignition or not.
That's how they should work
- are you saying they stay on if the button is turned off as well?
Because the car had been sitting since last night, I didn't
know how long this had been happening and of course Steve is doing a double
shift....not available. I phoned the mechanic back and he suggested I unhook
the battery cable from the battery and leave it off , which I have done,
until it can be brought in.
Whew!!! Any ideas what it might be or how much I will get dinged for
this one????
What I would do is put an
ammeter on the battery to see what the draw was when the car was off. Then
open the fuse box and pull fuses one by one until you see which one causes the
current being drawn from the battery to drop. You'll at least have a clue
what's causing it then.
