How you know

No cold air, or a compressor that will not engage. On a heavy duty pickup, cab configuration, drivetrain and box length all split this group, so the badge on the tailgate is not enough to order from.

The case for genuine GM

• 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.
• GM stands behind it. The a/c compressors warranty comes from the manufacturer, not from us.

Confirming fitment

When a component is superseded, GM documents why. That history is worth having when something failed early. Two vehicles off the same line in the same week can take different parts. The VIN is how we tell. Most orders leave the same day. Oversized and freight items take an extra day to crate.
