AC clutch not staying engaged

[kwhowell6539]

Hello all. My ac clutch will not stay engaged after 10 to 15 minutes. Fuse 11 was blown. Changed it but blew again. Checked pressures and everything was good (low side 25 and high side 185 at 1200 rpm). Ran good for 10 to 15 minutes then clutch started to only partially engage. Did this early in the day so not alot of ambient light in engine bay. I could see sparks as clutch was only partially engaging. Could it be the clutch going bad? Only does it after everything warms up.

2004 EB, 232k miles

Sounds like the clutch is wearing out. I don't know if that is an independently replaceable part, or if the entire compressor needs to be replaced. Depending on the mileage it might be a good idea to replace it.

Thanks GaryH for the response. Finally determined the clutch was gone. Went ahead and replaced the compressor, drier/accumulater and condenser.

Your AC pressures are low. Especially for the heat of Texas right now. You should be seeing 40 low side and 225-275 high side. Try adding some freon to the system and see how it does.

How's it working now? Getting some good cold air?

Yes sir GayrH.
