No cold air. The fan blows. The “AC” 10 amp fuse also blows. What could be the problem?

What does the 10A fuse protect? The fan works so it can’t be the fan fuse. 10A is too small for a compressor so it can’t be that either. It’s probably a control circuit.
In any case, there’s a fault that’s blowing the fuse.

It’s possible that someone substitued a 10 Amp fuse on the compressor circuit. Check the book to see if that’s the right fuse for the hole it’s in. If not, replace it with the correct one.
