I recently acquired a 97 k1500, and then I found out the heat didn't work .
I had an 05 Silverado years ago and had replaced the blend doors in it so I kind of just went that direction with some cheap ones off Amazon.
So I started off replacing the one for the vents near the gas pedal. While doing it I noticed neither the new one( I actually tried the two new ones) or the old one rotated very far at all, maybe a few 1/16ths of an inch back and fourth. At the same time I found out why the truck is stuck on defrost, the flapper for that one is messed up, it was unhooked from the bracket system and the rod and lever move about freely and in out. I don't know if I will actually fix that issue I assume the dash needs taken apart.
So Instead of replacing the heater blend door I took the dash apart and watched it, it does respond to me moving the control switch but in the same way as the actuator for the vents, barely moving back and fourth. I found a video on YouTube that clearly showed the actuators moving much farther back and fourth then mine.
I'm not sure what my next move should be? Replace the HVAC control switch ? At the moment all I care about is getting some heat in this thing so I can drive through the Indiana winter . My thoughts are send back the blend doors, and get an HVAC control unit. Thank God for Amazons return policy, really helps for shotgunners like me.
