AC compressor in 2005 Sierra 1500 Crew Cab

[Jdtracy1]

I have a 2005 Sierra 1500 Crew Cab that has had 3 AC compressors go out on it. The first blew in July 2011 and was replaced with a new, not rebuilt, AC compressor. That compressor blew in June of 2012 because the condenser wasn't replaced. Replaced the condenser in July 2012, a month after the 2nd compressor was replaced, when the mechanic realized that a simple flush wasn't enough to remove the crap stuck in the condenser where the first compressor blew. The compressor that was replaced in June of 2012 just blew, about 13 months after it and the condenser were installed. All parts were supposed to be new since I didn't want to deal with issues of a rebuilt compressor.

 

Do I have a bad mechanic or is there something else going on? Really don't want to throw another $1000 into a condenser, compressor, and everything else if it is probably going to fail in about a year. Truck has 101k miles on it, so am I needing to worry about other large issues that could come up besides the AC? Thanks for your feedback.

Did he replace the accumulator and orifice tube when the compressors were replaced? That is where the trash usually collects. Was some oil of the correct type add at the repair? Was it cooling good after it was repaired?

I believe that the accumulator and orifice tube were also replaced at the same time as the compressor was replaced. After the original compressor failed, the air never seemed to get real cold. I also have an '08 Sequoia and the air in that gets real cold. The air in my Sierra gets relatively cool, but never cold. Checked the ac charge multiple times and it always seemed to be good.

I'd say flush the whole system again, replace the compressor, orfice tube (filter), & dryer (cheep) ALL with AC Delco parts from an AC Delco parts store (cheeper than GM dealer). This way you also have a 1yr warranty too.....

 

Good luck.
