Hi, I am new here and I am looking for some help. I have an 05 Highlander and my heat went out. The dealer said that I need to replace my control panel, a 740.00 part. After reading this, I think that it may be as simple as a wire problem.
Last summer while driving with the air on, the heat would come on, and then go back to the cool air. It did it a few times and then quit. This fall when I would turn the heat on it would switch to the air and then back to heat. Now, the heat will not come on at all. My rear heat for the third row seating still works.
I am thinking that it may just possibly be in the wiring. Can anyone advise? I am a little afraid to remove this part on my own but my neighbor may do it for me, he is an electrician. I looked at the pictures that were posted and my control panel looks the same. I DON'T want to pay almost 900.00 to have this repaired at the dealership if I don't have to.
Any advice?
