Question about 2008 GMC Yukon XL
Sounds like the compressor is ok, but the orifice tube may be plugged, making the high pressure side shoot up to too high of a pressure rather quickly. When the pressure on the high side goes down, then the compressor tries to turn on and circulate refrigerant again, but can't for long because of the restriction.
There could be metal filings from the older compressors which were replaced still in the plumbing. Will have to evacuate the system and replace plumbing parts as necessary.
Hopefully your compressor is covered by warranty, but I would not count on it if contamination from old compressors was not properly removed by the prior service.
I would try to get warranty service, though.
