2007 Avalanche LTZ AC wont turn on
Mechanic has replaced the Compressor and the Condenser (pus freon) since the clutch tested out as bad and the fuse had blown.
While doing the diagnostic the AUTO AC board on the dash (display) would not light anymore and we replaced that as well.
Now, everything appears to work ... but the computers wont actually start the AC Clutch. Anyone have any ideas?
