Hi Guys
I have just changed out the heater core in my Blazer. Heater is working great now ,but I can not switch from heat to air conditioner, also with the blower off I still feel a small amount of heat comming from the vents. Vacuum is working cause I can switch back and fourth from vent, floor and defrost. I have checked the HVAC and it is tring to move but only moves just a little. How much should the shaft rotate and possiable causes to look for.
Thanks Keith
