A/C Clutch replacement 2002, 4.0L 6 cyl

I thought I had my AC running OK. Now it will work a few minutes, blows cold air, then warm air. If I turn off the AC it start again blowing cold for a few seconds, then stop. When I put a gauge on the low pressure port of the AC, seems to show the compressor stops running as it warms up.

Is this a sign of the compressor clutch failing. I have the factory manual. Read the steps for replacing the clutch. Is it a hard job to do? Anything to watch out for? If I can I'd like to replace the clutch vs the compressor and avoid the payment to evacuate, pull vacuum and refil.

Online prices for clutches vary from 160 at NAPA to 69 on ebay.

Yeah, there was a recent thread on here with exactly that. They were told to smack the clutch and it would start working. They took he clutch off and found that it was worn. The person bought a new compressor, but only replaced the clutch and kept the compressor for a spare. It was within the last two weeks, so if you look through the recent threads, you should be able to find it.

When you were checking the charge pressure did you observe that the clutch was working? meaning did it cycle on start spinning in the center portion and then shut off briefly regardless of what position the dash selector was on? If it cycles on/off repeatedly with you doing nothing else then you may have just a slightly low charge which can cause the low pressure switch to give the signal to the clutch to turn off till it comes back up a bit. That could mean you just need to add a slight amount of R134a or that you have a small leak. Otherwise yes you can buy only the clutch and replace. You can also unbolt it front the front of the compressor shaft and check the inside parts. In between the clutch and the shaft will be several washers which are called shims and you can remove 1 of them and reinstall to see if that makes any difference in how the clutch operates. I had the same problem a month ago, could not get it to work with the shim trick so i purchased a complete Compressor/clutch and removed the new clutch and installed that on my old Compressor which a month later is working just fine. And if it dies i have the new compressor in a box waiting to get installed. The strange thing is the price on just the clutch was about $25 less than for both parts together.

I forgot to follow up. I had too much 134a in the system. I bled a little, its been running fine since.

Good deal. Live and learn. I didn't know the compressor clutch would stop with too much R134a.
