I have an old style ('88-92) Tahoe/Blazer 2 door, with the old style dash and electronic AC controller. It has simply died, I have swooped it out for a controller that I know works, but there simply seems to be no power getting to the unit. I have checked the fuses all ok, and had the dash apart to look for damage wires with no luck. Is there another fuse? Any ideas?

 

Is it the same issue as the first unit?
