Detailed Description

Universal Air AK1321 is an A/C system repair kit intended for rear A/C-equipped vehicles in the 2000-2006 GM SUV and truck platform. This ancillary kit supports service work on the rear climate control circuit and is listed for 1st design applications where noted. Use AK1321 when servicing the rear A/C system on a 2006 Cadillac Escalade, 2002-2006 Cadillac Escalade EXT, 2003-2006 Chevrolet Tahoe, 2000-2006 GMC Yukon, 2002-2005 Cadillac Escalade, and 2000-2002 Chevrolet Tahoe with single outlet configuration.

For buyers searching by fitment, AK1321 is a direct catalog match for rear A/C repair on Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon models within the listed year ranges. The part number AK1321 helps confirm the correct ancillary kit during A/C service planning and parts lookup.

What It Helps Address

  • Rear A/C service on GM SUVs and trucks
  • Replacement needs for listed ancillary A/C repair components
  • Fitment matching for 1st design rear A/C applications
  • Parts lookup for Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon A/C repair
  • Service work on vehicles with rear climate control systems

Installation Notes and Tips

Verify the vehicle year, make, model, and rear A/C configuration before ordering. Confirm whether the application is 1st design and, for 2000-2002 Chevrolet Tahoe, whether the vehicle has single outlet rear A/C. Match the existing system layout to the listed kit references before beginning service. Professional A/C system diagnosis and proper evacuation, recovery, and recharge procedures should be followed during installation.

Quality Assurance

Universal Air AK1321 is cataloged as an ancillary kit for specific rear A/C applications and cross-references the listed component references for the same application. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
