Question about 2003 Chevrolet Silverado 1500
I took the dash apart and unpluged the controler. it worked for a day then went back to blowing hot air
Had exact same problem with my 2006 Chevy Silverado 1500. Would blow hot air thru drivers vents only and sometimes if I turned truck off and restarted would blow air conditioner for a bit. Rec'd recall letter from Chevrolet in January for this problem.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

common problem, check under dash by the gas pedal if control arms are muving went selecting from ac to heat cuz this it is the control for the vents to go from ac to heat and to defrost.

You need to replace the drivers side temp actuator that is located on the left side of the HVAC box. It is retained by 3 screws and is fairly easy to replace.

GM has a known problem with the electric actuators that operate the blend and temperature doors in the HVAC system. There are 4 or 5 of these in the typical system. Any can start sticking or binding and cause this problem. Sometimes they can be cleaned, or they might need to be replaced. Sometimes resetting the HVAC system controller by disconnecting the battery for 10 minutes, then reconnecting it, will correct the problem.
