My a/c stops blowing cold at times. I have traced it down to an intermittent a/c clutch. There is always power to the clutch when the a/c in on. On hot days the clutch will disengage if you take a wooden down and just lightly thought the outer edge of the clutch it will engage again. system is charged properly and all senors are good. I concluded it is weak clutch. See this a lot on Dodge trucks. Had anyone taken the clutch apart and cleaned it. I'm being cheap. Don't want to spend $200.00 plus on a compressor.

you may be able to just adjust the airgap between the pulley and hub. Chase the specification down and check yours.

There's also the possibility of replacing just the clutch. It will probably require special tools but those can be rented from a well equipped parts store.

IIRC, OP works at a Chryco dealer. So, special tools should be somewhere there.

Eric, which vehicle is this for? I have my original Renix AC comp sitting in my garage.

My cost on a chrysler clutch is more than a compressor from the parts house. All the parts houses list just an a/c compressor

Remove the clutch plate and take some shims out.

If that fixes it you saved $200.

If it doesn't, buy a new compressor.

md is right, your best bet is to take a shim out. You'll still need a modified spanner wrench to grab the clutch, but if you've got access to specialty tools that won't be an issue.

Best of luck!

Take a look at my thread addressing your same situation. This has been working for the last 4 years without any trouble and took 10 minutes costing nothing.
