I bought an older TT that had been abandoned in a field for a few years. After chasing out the mice and fixing a few things, I decided to test the A/C. It was too cold outside to tell if it was really...
I have discovered it is not the compressor, but the blower fan that pushes the air through the vents. The thermostat was wired wrong. A little Internet research put it straight.
I will definitely check that out. I am scared to go on the roof, though. It doesn't leak and I don't want to push my luck. :/
