Air Conditioning

I have a 1990 Cutlass supreme and i keep blowing fuse #7 which is a 10 amp fuse that controls the Air Conditoning Relay and Clutch, and Fan Relay. My A/C compressor doesnt kick on but the it blows air thru the vents. I cant figure out what the problem is anyone have any wiring diagrams?

I lent my book to a friend, so i can't look up the diagram, but it sounds like you either have a short, or the AC COMPRESSOR has fried. The AC compressor does NOT control the air blowing through the vents.

When you turn the AC on, does it still get REALLY COLD? Does it blow the fuse immediatly, or only when you turn it on?

The Fuse blows as soon as i turn the key to the on position, before i crank it.
I Replaced the black Relay in the outside fuse panel and the fuse still blows.
A/C blows no cold air at all only outside air and compressor clutch is not kicking on.

TRy to disconnect the plug for the AC COMPRESSOR, and see if it still blows the fuse.

There is a small 2 wire connector between the main body of the compressor, and the pulley. Unplug that, and see if the fuse still blows.

im guessing its the compressor clutch im going to wire test it tomorrow.
