[wayne]

I just replaced the blower motor control module and now have control of the fan speed now but i still only get hot air from the rear and passenger side also i cannot change the mode it only come out of the vents. anyone have the same thing going on and how to fix it?

Sounds like you have a couple of more issues going on... First, it sounds like your a/c system needs freon. Second, it sounds like your hvac control module needs to be replaced. I was only able to find the control module at the dealer ($$$) for my tahoe.

Good Luck. Mike
