A/C Help!!!
What happens when your A/C compressor goes out? Does it just stop coming on? What about the A/C clutch?
A friend of mine took his car out and turned the A/C on, but nothing, but the fan with hot air. He replaced the fuse and it wasn't that.

The compressor would stop coming on just like that? He hadn't driven it in about a mouth. It was working just fine before he stored it in the garage for that period of time.

Check the freon charge first but the other thing that can cause it is a blown coil on the a/c clutch. That's easy to check, just unhook the wiring on it and do a resistance test across the 2 wires - or apply 12v directly to the clutch wires and see if it engages. If that's OK you can also check for 12v on the wires going to the clutch.

All of the above is good advice.
A quick way to check for low Freon is to pull the electrical connector off the low pressure switch. With a wire, short across the wires in the connector. If the compressor clutch engages, you can bet that there isn't enough freon in the system. Of course the pressure switch itself could be bad but that's not likely.
The A/C must be turned on when you do this test.

Well, I just talked with him and he found out there was no freon or very little in the line at all. So, I guess we now know why there wasn't any cold air.
