SOURCE: Hot and Cold

The most likely cause of your problem is the blend doors under your dash. If they are not moving like they should it can cause this type of problem. You can look under the dash to see if there are any linkages that are disconnected. Some of these are very hard to change so you might want to take it to a repair shop unless you are very good with cars.

SOURCE: 99 STS AC is blowing hot air

I had the same problem but it was blowing hot air on the passenger side of the car. I assume you have the dual zone controls that I have as well. The problem is most likely the damper that controls the flow of hot and cold air into the car. The motorized component of the damper is most likely not working and its stuck in the hot air position.

I had mine replaced by a repair shop so I cant tell you how to replace it but it may be something that you can do if you have the time and patience to work on it.

Good luck

SOURCE: driver's side defroster and heater vents blow cold

The doors that open and close in the heater control unit are ran by motors. It sounds like a motor has quit in yours. When turning on the defrosters the motor closes the door to the heat for the floor

When air conditioner is turned on the drivers side blows cold air and passengers side blows hot air, rear dual air blows cold air in to back passengers area.


If your sure you're looking at the right motor, Then the door is broke. Dash and plenum have to come out to fix it. Not a cheap fix.

Air conditioning system, when you turn on the air conditioner the drivers side blows cold air and the passengers side blows hot air? What causes this problem?


The most common cause of this is that you have a stuck air temperature control blend door, this can be a motor actuator issue or a jammed door or both (common). To replace both parts you will need to completely remove the dash from the car to access the blend door.

Left Vents blow warm/hot air when calling for cold air


Usually a sign of a faulty blend door under the dash.
The blend doors direct air thru the ac and heater core along with the upper and lower vents.

I have the daul air conditioner and the driver side blows cool air, but the passager side blow hot air even if its on cool....help!


In the dash there are multiple "Mode Doors" that direct the flow of air in the dash for your AC. A duel zone system takes it further than that because it has doors for each zone.

Most likely, the temperature mode door for the passenger side isn't working properly because of a bad motor or other issue. There is a service bulletin on late model Chevrolet trucks that states as the motors age, they begin to work outside of the specified range the computer expects. As a result, they hang because the computer doesn't register them working correctly (out of range). It is recommended you have the vehicle software flashed to the latest configuration prior to diagnosing this issue as the new software takes the motor wear into account.

A/c blows hot air on drivers sde


The actuator door on the driver's side is out of position and needs to be reset. Remove the negative battery cable for 1/2 hour to reset the computer. Start the HVAC system and you should be able to hear the door adjusting itself and cold should come out of the driver's side vent.
