Hello, I am having a problem with my HVAC. It al started happening when I disconnected my battery to install a new air bag sensor. I reconnected the battery and now when I turn in the truck I get cold air for about 10-15 seconds from the drivers side then it turns warm-hot. When I turn the AC on the drivers side continues to stay warm while the passenger side is ice cold. I'm thinking a blower motor actulator but where is it located? How many could control the drivers side? What's the part number? I have a 2004 Chevrolet Silverado 1500 with Manuel climate control. Thank you for your time!

Pull your hvac fuse form inside the truck with key on for 60 seconds it may make the actuators reset and fix the problem.

Then have it scanned for codes by a pro it may be the control head or actuator.

I tried all the "home remedies" I could find online and no luck. I also took it to three different places to get it checked and no code. I am just going to buy a new actuator and install it. I want to personally thank you Hmac300 for your help and fast responses. It seems like a lot of people have this problem.
