Symptoms to look for

No cold air, or a compressor that will not engage. On a mid-size SUV, suspension type and towing package split this group, and neither is visible from outside the vehicle.

What you get ordering from us

• Factory sourced. These a/c compressors are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical a/c compressors numbers for you.
• Ships from Dallas. A/C Compressors ordered by 3pm Central go out the same business day.
• Straightforward returns. No restocking games on a/c compressors that did not fit.

Ordering correctly

Aftermarket versions are often close enough to install and far enough off to cause a repeat repair. Option packages divide this catalog more than model years do. Send the VIN and skip the problem. Our Dallas location means most of the country is inside a two or three day ground window.
