You have a bad transition valve or disconnected vacuum line on said transition valve that moves the blend door open and or closed under the dash. If you have the heat on and heat only goes to driver side and still cold on passenger side, then the problem is at the passenger transition valve.

SOURCE: heat works on driver side, passenger side blows cold air.

Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.

SOURCE: 2004 Chevy Silverado AC is blowing warm air on passenger side.

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

SOURCE: Changed batteries and climate control not working properly

The actuator has gone bad. They can be programed, and reset, but usaly they are bad, and that will only patch the problem for a while.

SOURCE: 2004 chevy tahoe, dual climate control, blowing different temps

Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck

Take battery cable off for 5 mins, then put battery cable back on. Insert your key into the ignition turn to on but don't start the vehicle wait 5 seconds turn back off repeat the key on/off three times. This initiates a re calibration of climate control equipment and actuators. It will fix your problem.

Just had this happen today to my 2007 silverado heat on the right side cold air on the left side. After engine was off 15 minutes and restarted heat was on both sides. I'm guessing a relay failed to open door to allow the heat to flow thus blowing cold air.will monitor diligently for a while.
