My ac blow hot do not hear compressor turn on 90 Toyota gt
It is very easy to check an a/c compressor clutch. Looking at the compressor, you should find a wire running from the pump the wiring harness. There should be a connector where you can disconnect the wire from the main loom, disconnect it and connect a length of electrical wire to the wire going to the pump. Connect the other end to the battery positive and you should hear the clutch clicking in. If you don't, the clutch is bad.
If it does click in, you should look at the fuses (should actually look there first) and the relay if it has one. By the way, if you connect the wire as described and you hear the click, you could actually leave the wire in place and start the engine and you should feel the cold air.
