SOURCE: 2004 suburban rear a/c only blows hot air

ase mechanic:
there are separate actuators for the blend doors. one for heat and one for cool. they work opposite and in conjuction with each other, if that makes any sense. ones open, ones close, for each different climate. sounds like the the cold one isn't opening in the rear.

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

The mode selector is bad. IF you look at the plenum (where the fan motor is ) you should see two levers one is hot cold the other is mode. Check them by moving the controls and see if they move.
If the mode lever moves then the door on the inside is broken or something could have fallen in the vents and is blocking it.

My air conditioner on 2007 suzuki reno blow hot air


it will need service,
check pressures.
hot air as in heater on, so turn off the heater,
test in pure A/C mode Cold.
when both A/C and heat are on this is called defrost mode
which adds cold dry air to hot air and dehumidifes the hot air and window.

The air conditioning is supposed to blow only cold air. Are you trying to get the heater to blow hot air? Make sure the temperature selector is in the hot position.
