It will work for a minute or even up to twenty minutes. Then it will blow the fuse it is like it has got a short up. I cannot find one. I fix the connector that powers the AC clutch. And it is still doing that same thing. It is full of refrigerant. Any other tips to fix it?

Good morning.

If the fuse keeps failing, then there is too much current draw on the circuit.

The first thing I would do is to remove the connector from the AC compressor and leave it disconnected. Turn the key on, turn the AC on and see if the fuse still fails. leave it sit for about fifteen to twenty minutes.

If it fails then you have a wiring issue to the compressor.

If it does not, then the ac compressor clutch is causing the high current draw and the compressor needs to be replaced.
