I need a diagnosis.
About 30 miles into our 1300 mile road trip, our AC ceased being cold. 10 minutes later we hit some traffic that was going about 30mph and the AC kicked back on and last for about another 30 miles. We hit some more traffic, dipped down to 30mph, and went back up to 70mph. Once we hit 70, the AC died for good.
Details on the car: 2008 Saab 97-x with the 5.3. 115k miles. AC belt has been changed. Belt is moving, but there is a nice whine coming from that area. When I hit the AC button, I don’t hear any difference in the whine or hear any other change in noise (ie clicking).
My guess is the compressor clutch gave up the ghost. Your thoughts? Here’s a pic of the NY Turnpike. It’s been over 90 degrees all day.
Also, why does my Android keyboard randomly disappear while typing in Kinja?

If the compressor isn’t kicking on (You should be able to see it spin):
Cheap things:
Relay (swap out with a known good one to test)
Pressure cutoff switch
Worn out clutch with too much of an airgap. (remove shims)
Expensive things:
Clutch / coil / compressor
A/C mode switches

You need to know how much refrigerant is in the system. It might just be low. If that’s not it, my money is on compressor or compressor clutch. Might even be the compressor is leaking. Pretty common GM problems.

Since there is a whine noise, and it was ice cold before the whine popped up, I assume it’s something mechanical. At points in the trip, the whine was quite loud.
