What can I use to find a damn leak in my A/C system? Any suggestions.

For starters i would just trace the lines till you find a oily spot. Look around the compresser since that's were most leaks are.

now that we are on the subject my compressor doesn't kick in when I turn the a/c; any good ways to trouble shoot the compressor?

1. Swap the a/c relay with a good one, and check your fuse.
2. I would ohm/continuity test the high and low pressure switches to see if its low or has to much. You should have continuity on both switches.

Before you test any thing - see if there is pressure in the system. Take off the High black cap in the front push the ball in with something - If there is no pressure - you have a leak - 99% of the time its the compressor.

If there is pressure follow rocketfafst's instruction.

Edit:
And there is no way to 'test' the ac pump - either it starts or it does not.

If you have pressure you will get continuity on the low pressure switch. All the pressure switches are wired in series.

Check the pressure level on the system first, then try the relay, fuses and harness.

I know mine is a leak because I can hear it but just can see where its coming from. I think I will get it on a lift during my vacation.
