Where is the heater core located on a 2002 Yukon XL?

Answers from the Automotive Experts

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Betina, Most heater cores are located under the dash on the passenger side of the vehicle. I believe the Yukon has a front and rear heater so you may want to check with the dealership to find out where they are both located. Lori Johnson
