heat/ cold air problem after heater core - 8/23/2008 1:05:44 PM

My girlfriend has a 98 Bravada, which is pretty much the same vehicle. I replaced the heater core. The problem is now it only blows hot air, no matter what setting it is on. I read plenty of topics on no heat but this is no cold air. Did I mess up something with the door when I put it back together?? Or something else? If it is the door, will I have to pull the whole dash again to fix it. I did this awhile back and forgot how it all went together.

Thanks for your help!!

Does sound like there is a problem with the temperature blend door. I would check to make sure that you connected all of the vacuum and electrical connections first.

I will check again. If it is the blend door will I have to tear everything out again to get to it. It has a split cover, top and bottom. Just wondering where the linkage bolted up as I can''t remember. Also is it even possible to bolt it back up wrong? I figured it would bolt up in the same position I unbolted it.

Thanks
