    Thanks so much for the post. I have 2004 chevy tahoe and my issue was the front vents were blowing cold air but the back vents were blowing hot air. The part number you recommended fixed it right up, thanks again…

    I am looking for a video on coolant leaks in the rear. I suspect either lines or heater core. Any ideas?

    just fixed my heat. this video is spot on! Make SURE to remove the fuse(s) then run the engine for a few minutes. then turn it off, and then put them back and your DONE! I removed fuse and ran engine only 45 seconds , and it wasnt long enough!

    Can I trouble you with a question? I originaly had no rear heat in my 03 Tahoe, I replaced the control module as you suggested and WA LA! We had heat, so I thought I would check the rear AC and it blows warm air, the front AC blows cold. Should I be looking at the rear heater/AC blend door actuator or could it be something else? Thank you.

    If there's heat but no a/c this procedure will fix it, right?

    Thanks sooo much! Your video was awesome! I'm a single mother who doesn't have extra money and your video showed me exactly how to replace the control module, down to needing a 9/32 socket. I bought the part on ebay for $64 and it took me 20 minutes from start to finish. Thanks again!

    I just replaced the control module and now I have heat again! Amazon is your best bet…the dealership wanted $150 for the module, and you cannot get it from Autozone, Napa ect, AC Delco is the only company that makes the part. Also, just to make life easier, just unhook the negative battery terminal for a few minutes to reset/recalibrate the system (the fuse trick didn't work for me). Great video though!

    Spitfire1821, you rock man. Your video just helped me fix my rear heat on my 2004 Tahoe. Now I can take the kids without their snowsuits on in the back. LOL. It works great now. Thank you so much for taking the time to make and share this video.

    After installation, why do you turn it on and then insert fuse? Does that reset the system?
