Hi All!
My 2003 H2 will only blow heat when set at 90 Deg., not 75 or 80 or even 85, 90 degrees! I recently moved from OH to WA and never experienced this issue in OH where we have very cold winters. The dealer in WA say that this is normal? I have searched the forums without any luck, Please help.

Could be your blend doors. which are a major pain in the *** and will cost like $1000 to replace or if you try to do it yourself its like a 10 hour job or more.

I had similar problem where it would only blow when the fan was on the highest setting. Replaced the blower control module and it was fixed

Is the Blower Control Module easy to access? Where abouts is it in the engine compartment? Thanks.
Just want to confirm the P/N from ACDelco is # 15-80655 or GM 93803637.
