Quick facts
- Part: Four Seasons 1739NK A/C compressor mount and drive kit
- Fits: 1999-2002 Chevrolet Silverado 1500 and other vehicles
- Position: Front
- Condition: New
Warm air from the vents, a noisy compressor or a compressor that will not engage can mean the compressor is wearing out. A low refrigerant charge from a leak can also leave the air warm, so these signs alone do not prove the compressor is the problem. This listing is one kit, and each vehicle takes one.
Fits
The 1999-2002 Chevrolet Silverado 1500, the 1999-2002 Chevrolet Silverado 2500 and the 1999-2002 GMC Sierra 1500 take this kit, and so do many other Chevrolet, GMC and Cadillac trucks and SUVs. If your truck is not named here, look up its year and model in the "Vehicles it fits" section further down this page.
