Kcarden,

You will find that the Damper Motors are much like the Instrument Cluster Gauges, Speedometer and Tachometer in that they are controlled by Stepper Motors. The Original Equipment Stepper Motors in the Instrument Cluster in 2003-200? were prone to failure. The after market replacements typically will solve the problem.

Unfortunately, accessing the Stepper Motors in the Heating A/C Plenum is a time consuming job and there will be many minor difficulties in replacing them. Unless you have a lot of experience Soldering delicate Electrical/Electronic devices it is recommended that you consult a professional to have this problem properly diagnosed and/or repaired.

First of all you need to be a contortionist to physically be able to get into the cramped quarters under the Instrument Panel and then you need a good selection of 1/4" Drive Metric Sockets and extensions. Having those tools available will allow you to gain access but finding the Stepper motors may require removing the entire Plenum and disassembling it. If you have lots of time and patience it may be possible to do it yourself. Having a good repair manual for your particular year, model and make vehicle is where to start.

A Simple Test is to shut of the Heating A/C System by turning the Ignition Switch to OFF then re-starting and see if the problem goes away. Another thing that possibly could cause it is a defective (Intermittent) Accessory Contact in the Ignition circuit.

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

SOURCE: one side air blows cold one side blows hot

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.

My 2004 Chevy only blows warm air on the passenger side my driver side is always cold. It has a dual air systems, but my A/C works great on both sides. What can i do to fix this problem ?


i am an owner also same vehicle there is a baffler in the center of the console next to the front window it you can find it cause there is a little hole you cn see this controls the air distribution to the driver side . i tried getting to it twice it is difficult to remove all that. Was close but ran out of time and gave up was quoted over $300
to repair if i removed the steering wheel it might have been easier to solve . good luck

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.

You have a faulty switch. Go to the salvage yard and buy a used one, pull off the trim panel and replace it. I just did one of these last week with the same symptoms.

Check movement of vent doors on that side. Sounds like they aren't moving over as they should. (Or hose fell off on passenger side.)

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

Intermittant hot/cold air from heater


Had the same problem with my Mazda6 awhile back. Took it to the dealer and they found the radiator wasn't holding pressure. They replaced the whole radiator under warranty (WHEW!). Not sure how to check for that kind of thing, but it's a start.
