No heat in cab during winter!!!
#11
Update:
I have been putting water in the radiator regularly and squeezing the hose until I can pull it which will hopefully be this weekend. Anyways after some research I am sure it is a problem with the heater core. The blend door works, it's weak sounding but it does turn. The hoses leading into the cab were the heater core would be are cold.
I changed the thermoset just in case. I find it odd the hose leading the HC are not warm when the truck is.
Going to try and flush it tomorrow. Hope this works!!!

I have the opposite problem. My 1995 K1500 blows strictly hot air and when I move the temp switch there is no difference in tempertaure. Pushing the AC button has no effect either. Recommendations?

when you hit the AC button and switch the temp to cold you should hear the rpms drop on motor then pick back up. make sure your compressor is engaging the clutch and if it is not then it could just need a recharge. if you recharge it and it still doesn't work then it may be a compressor problem or the climate control panel.

if the temp of the heater core inlet and outlet hose are the same the core is plugged.
the inlet hose should be hot, the outlet should be at least 10'C cooler with the blower on high.

Try flushing your heater core , if that doesn't work then you need a replacement.. If you decide to flush the heater core do it multiple times , me and my dad had to try 3 times , then it started to work.. We had the same problem for my friends silverado
