      Description

      A Time‑Saving Rear A/C Solution. The Auxiliary Air Conditioning and Heater Line Assembly delivers a direct‑fit replacement for the auxiliary evaporator to the auxiliary heater line. This assembly is used on GMC Yukon models from 2007 through 2014 (excluding Denali Hybrid). It facilitates proper rear climate control by routing refrigerant to the auxiliary heater efficiently and reliably.

      Construction and Appearance. This multi‑piece kit is constructed using durable aluminum tubing paired with rubber sections, featuring threaded fittings for a leak‑free seal. The assembly includes new O‑rings and gaskets, and the finish is silver/metallic for corrosion resistance and OEM style aesthetics.

      Installation. Installation is moderately difficult and may require access to tight rear‑HVAC components. Threaded fittings simplify the process—minimal drilling is needed if you follow the original routing.

      Warranty. This part comes with a limited lifetime replacement warranty via Advance Auto Parts and NAPA listings.

      Application. This Auxiliary Air Conditioning and Heater Line Assembly fits GMC Yukon models from 2007⁠–⁠2014 (excluding Denali Hybrid).
