I pulled the CCU unit out, all the solders seemed ok and there was no reason for me to believe there were dirty contacts. I believe the problem has something to do with the compressor.

I first noticed a clicking noise today, and it appears to be coming from the compressor. (It looks like the clutch is not engaging). I tried jumping the low pressure switch to see if it would cause the compressor to engage however showed no difference. I tried charging it with some R134, however it caused the fuse to blow all together. Any other ideas?
