Question about 2003 Saturn ION
HVAC system is 'automatic climate control' type. Set the temp and the car does the rest. Here's what I know:
Heat Works Fine
System has been tested, no freon leaks.
Problem: A/C does not kick on regardless of temp setting.
the unit blows warm air. This was sporadic at first, no cold air at all now.
Took car to saturn dealer, they claim they cannot determine if the problem is with Body Control Module or HVAC control head. I have a 50/50 chance, replace one, if that does not work, replace the other. Cost $500 each. (no refund if the first fix does not work).
They tested the BCM and claimed it was having trouble communicating with the HVAC control head, but they couldn't guarantee that is the problem.
Any thoughts? I don't mind paying for repairs, this seems a little out of line.
I worked at saturn dealer for 18yrs.Those auto hvac heads are a weak link on the L-Series.But I have to say the BCM's are totally junk!! But if it was me I would go with the BCM because you can get a used HVAC head from junk yard but the BCM has to be new because it has to be flashed.If It was me I would try to get a used hvac control from salvage yard.Also yo might want to get a 2nd opinion because those L-Series cars are all bad for Compressor concerns.Hope this helps
