Default Heater motor
I have a 2001 Chevy Sliverado 4 door. The heater motor runs on all speeds, but does not blow out the vents (front or back) hardly at all. Could this just be a hose off?

It could also be the blend door actuator stuck closed on the hot side. However, if your truck has climate control this is likely not the issue if both sides are messed up.

correct. temperature works on both hot and cold and the motor runs fine, but the air does not blow hard out of the vents.
