Run power directly to the compressor to see if the clutch locks. If it doesn't you may need to replace it. Also, make sure it is fully charged. Low freon will prevent the compressor from locking in.

I am so sorry I never got back to you. It didn't show up in my email till now. Have you gotten the problem fixed? As far as the freon, you need to check pressure in the system. You need special tools to do it.

Glad you're in a band. I have been since I was 12. lol
