I can't figure out how to attach a photo here. I can e-mail if you'd like. The AC ***** are rotary though.
Has anyone heard of a defective AC part that Saturn installed in these cars? A mechanic told me that Saturn is aware of it but I couldn't afford to go to the dealer at the time. It's unusual that a unit won't deliver heat or cold with a working blower fan.

 

Nope - not unusual at all. The reason I know, it has happened to me on my 2002 L-car. The coupling on the **** fails (it's only plastic, and not very sturdy at that). OEM part, so you'll prolly have to let the GM dealer near you order one up. It's an annoying little bugger to get aligned properly, so you might be $$$ ahead by letting them do it for ya ....

 

Thank you OA, would they be able to determine that it is indeed this part?

 

Indeed yes .......

 

Thanks again Mr. OA.
In an effort to eliminate all the simple possibilities let me tell you that if I'm in the car with the A/C fan blowing, with the temp **** turned to the right (heat), I then turn the temp **** all the way to the left (cold) and the fan speed increases. So the fan is responding to the temp ****. Does this eliminate the possibility of the temp **** being the problem?
