Hi, I have a 2007 Tahoe yesterday for the first time I was herring a horrendous noise so I switch off the AC and it went away, I turned it back on and it was gone. Today I did here it for a second and then it was quiet. has anyone had a compressor go bad? I just put one on my 2007 impala a month ago I hope not this one too.

what kind of noise was it like a jack hammering type noise? Did it sound like the belt was skipping over the pulley?

I would say hammering more than belt. It was weird that it went away usually the hammer and that's it.

it could be that your Freon R134 is freezing and slushing up causing the compressor to sort of skip along almost to the point of locking up. I'd have some gages put on it to make sure it is not low. Check the orfice tube. I know on the early 03 this was a big problem remedied by replacing the compressor.

It was right when started after sitting 8 hrs at work I wouldn't think its freezing but you never know, the next time the AC guy comes out I will have him look at it.
