im stumped. I have a 2005 Tahoe with the sliding style climate control and I was going to replace the bulbs in my climate control but after attempting it I decided my soldering skills are quite terrible. So I went to the junkyard and picked up a sliding climate control out of a trailblazer they look the exact same and the plugs were the same. Everything works except now cold is hot and hot is cold. Anyone have any idea what is going on?
