I’ve owned a lot of vehicles, but this is a new one to me. 2015 Yukon 5.3.
My AC compressor locks up. The cooling seemed to be working fine up until then. It burned through the first belt in my driveway upon start up.
I hand spun the clutch outer pulley and the center compressor hub. Both spun freely.
I replaced the belt and within 60 seconds of start up, the compressor locked up again.
I’ve never known this to happen to anyone before. I’ve got an appointment at my local shop on Tuesday to have the system flushed out, compressor replaced and do a full recharge (R134 I believe).
Three years ago I replaced the entire Ac system on my late model GM car and also on my import car following compressor failures on both of them where they stopped operating — but not locking up. I bought a vacuum pump and a full set of gauges and it was very straightforward and successful.
I didn’t mind replacing everything on those systems because I was concerned about contamination and the age of the vehicles justified new parts. I don’t have the time now to tackle the Yukon’s system
But on my Yukon, I am concerned that if there is any debris, it will foul the front orifice tube and/or the rear expansion valve. The updated condenser has already been replaced. New receiver/dryer while I’m at it?
I would sure welcome your experiences and thoughts before I spend the $2k getting this changed out.
