Question about 2001 Chevrolet Silverado 1500
Check the blower inlet. There may be something blocking the inlet. If that is clear the heater/ac core may be matted with hair and dirt.

It will be a cable that will be disconnected. or broken. Youll have to take some of the dash apart to see the cable and follow it to the switch. Dont be affraid to take some things apart and when you cant see, use a mirror to help you see behind the dash. work the control and watch the action. You will fix this dont get frustrated. good luck

If your talking about no air flow, at the vents, floor,defrost, there are no doors that will restrict air flow, then you have a plugged Ac evaporater core, with foriegn matter, leaves, dirt, and oil from the ac itself, leak in evap leak cause this, as long as the blower is working on all speeds, remove the motor for inspection and evap , an other way to inspect the evap, remove the evap sensor grommet, look inside of hvac, the core will be plugged, this is an expesive repair to do. GOOD LUCK. RDJRP
