2001 tahoe front heater not working, rear heater blows warm air

We have a 2001 Chevy Tahoe with front and rear heating and a/c. Currently the hot air is not blowing out of the front even when the temp knob is turned to the hottest setting. I believe it may be the actuators. Where are the actators located and how can I get to them. Are they behind the glove box?

  • dunlapac Jan 21, 2009

    did you find a fix for it. i have the same problem with the front heater blowing cold air instead of hot but the back blows hot. My tahoe is a 2001 as well. I wonder if this is a universal problem with the 2001 model.

I have the same problem with my 2001 Tahoe. The front blower is working, its blowing strong, but its cold air even with the temp setting as high as it can get. The rear blows hot air. The engine temp guage is at about 210ish which is close to being normal (220). I just replaced the thermostate a few months ago, I don't know if its bad again, or it I deluted the antifreeze too much and it frooze the heater core, or if the heater core just went bad. Any one know what the cause could be?

I am also in the same fix. 01 Tahoe; rear air is blowing but the front is not. Has anyone found a solution on this yet? I'm fixing to buy a new Temp Control panel and see if that fixes it. Any thoughts?

Is the fan blowing but the air is not coming out where you want it, or is the fan not blowing at all? If the air is not coming out where you want it, the actuators are the cause due to having no vacuum. If the fan does not blow at all, it may be the fuse or resistor. I offer this advice being unable to tell you where to find the resistor but it should be near the fan housing. I would try pulling the glove box if the fuse looks good.

Chevy 2005 tahoe z71 blows cold air in back but hot air in front

Just got an answer from Chevy Dealer. When you replaced the battery it loses its memory as to where the door actuators were (the flaps that control the heat and A/C).

The fix:
Turn everything off and let the car sit overnight. The computer should reset itself during its learnings process.
In the morning turn on the ignition and let the car run for a few minutes before turning on the climate control.

If this doesn't work, plan on 1-1.5hours of labor for a technician to reset the actuators at the dealership.

Good luck.

04 TAHOE Front A/C works great, Rear A/C blows warm. Seems like something isnt shutting the flow of hot water to the back??

Hi Jason.
Sounds like you are on the right track with the flow of hot coolant not stopping. Check your heater control valve to make sure it is stopping the flow of coolant through the rear heater core. Let me know. Hope this helps.

2002 Chevy Tahoe, started with rear a/c blowing warm/hot air, then it started working again. Now both rear and front a/c blows warm/hot all the time. All speeds seem to be working in front and back....

sounds like a leak. Have your system checked for leaks and re-charged. If the system is full of refrigerant, then check the pressure switch on the compressor and the pressure switch on the accumulator (dryer). If the pressure in the system is low, these switches prevent the compressor from running to prevent damage.

2001 tahoe front heater not working, rear heater blows warm air

Notorious for plugged heater cores. Also updated plastic restriction couplers mounted at heater core available from dealer. Try back flushing heater core. Run engine till its at operating temperature then carefully hold the inlet and outlet hose breifly with heater fan on high if hoses are nearly the same temp then flow is good , if not then core is plugged.
