SOURCE: vehicle: 2004 chevy silverado problem: when

As long as you did not have to go into the dash to splice those wires, I would say that you have either a Tempreture door that is Broken, or the actuator that controls the passenger side temp. door is bad. Most likely cause will be the actuator, because they have a very high failure rate. The actuator is located is located on the very top of the a/c-heater box behind the radio and a/c control head. It will be rather hard to change because every thing fits so tight. But if you remove the radio and the A/c control head you should be able to find it. Let me know if you need further assistance.

SOURCE: 2004 chevy subarban blows cold air on one side hot air on other side

i was a GM mechanic for many years, the problem you are having is one of your mode door actuators has gone bad, most of the time it is the actuator on the drivers side that causes the problems, i have seen this many times, sometimes you can take it to the dealer and they can hook the computer up to it and recalibrate it but most times it has to be replaced , it is located under the dash in the area above your gas pedal.

It sounds like the HVAC head needs to be recalibrated, most likely when you unhooked the battteries you lost the memory to the control head, it's in a default position/state.

SOURCE: 2007 Chevy Silverado dual climate control, even if

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.

Air conditioner blows hot air after 30 seconds on drivers side, on start up. Passenger side works fine. Air blows out correct vents per setting on air conditioning. Replaced blend door actuator on drivers...


I have had this problem. I am not a mechanic...so to correct the issue temporarily, I simply turn off the car and restart. This has worked everytime for me. In extreme cases, I think you can also remove the AC fuse and start the car, which will also reset the computer. I also think that by taking the climate control off the "AUTO" setting has worked in the past.

It sounds like the control motor switching from hot to cold is stuck halfway in between the two temp settings. You will have to take it down and replace it, it is mounted under dash passenger side near the blower motor.
