    Sorry that was a dumb question. The controller in the overhead, does that adjust the rear auto climate control in the auxiliary or is there a control module for the rear besides the rear seat over head controller?
  • Have you had any help getting this fixed any ideas would be appreciated
  • There were two controllers. One at the front of the vehicle just above the rear view mirror and the other in the head liner centered just behind the front seats. The controller just behind the front seats in the headliner was removed by a previous owner to install a DVD/TV screen. The only controller for the rear air now is the controller just above the rear view mirror. After the addition of the TV screen the single controller did operate changing the blend door correctly. Today the fan speed controller works correctly, the adjustment for air to be at the feet or out of the headliner works correctly, but the temperature adjustment does not adjust the blend door.
  • My 2007 Tahoe's front A/C vents do not have air coming out of them. It appears that the vent control is stuck on the floor and windshield and will not change. Any ideas on what could cause it to quit working?
  • I have a 2005 Tahoe and luckily I purchased an extended warranty when I gave the car to my 21 year old son to drive during his last year of colege. The vents started act strange: with the AC on they would blow only hot air. To stop the hot air, we had to turn the car off, wait about 10 seconds, and restart the car. We took it to the local dealer and their test equipment showed that they needed to "replace the air inlet, left mix, right mix and mode actuators". The total bill for this was $1909.04. The company that sells the extended warranty sent a rep to verify the problem before they would agre to pay to fix it. I'm glad I only had to pay the $100 deductible. My 2005 Suburban has had the same problem a couple of times, but I have no extended warranty. Maybe I need to buy one soon....

    I have a 2003 tahoe with front and rear automatic climate control. the front works fine. the rear unit fan, and one of the damper actuators work. it switches the air from ceiling to floor when the control knob is moved from cool to warm. the actuator that switches from cold to warm or blend does not work. if the entire cabin is cool from the front ac the rear fan will slow down as is it is supposed to. there is hot water going thru the heating coil. the cooling coil does not get cold and thus i get no cooling in the rear. i really don't care if i get heat in the rear but i need cooling in the rear as i live in louisiana and it gets quite warm here. also the rear aspirator makes an intermittent knocking noise, come and goes. does anyone have any solutions. the refrigerant charge seems to be ok with the proper guage reading.
  • I had similar problem for front A/C for two years, found good mechanic and he change heater control valve that fix my problem. Part cost me $68 and $80 labor.

    I have an 07 Suburban. About a week ago the air quit working. It still blows, but just hot air. I have checked all fuses and relays ( I think). I don't hear the compressor kicking on or off. Any Help??? I hope it's not the compressor as I am about 12,000 miles out of warranty.

    I had the vehicle checked at local dealership. It was a leaking seal. Thank goodness. $235.00 later we now have COLD air again.

    I am having the same problem. Is there a sensor that needs to be changed or protected?

    Thanks so much for any help that you can provide. I do not want to have to spend hundreds of dollars that I do not have to find out that it might be something simple and inexpensive.

    Thanks for helping-our 2005 suburban air-conditioning fan only works on fan setting bar 3, on the other settings the fan shuts off. The rear fan has no problems. Is this a function of the controller going bad or does it have to do with vacuum lines?

    I was looking on the site for the exact same problem with my 05 Tahoe T... Help any idea. single mom in AZ :sick:

    '05 Tahoe with digital climate controls and dual AC. The front AC does not blow anything at all when stopped, when you start moving it starts blowing after about 20 mph. It will only blow at 1 speed regardless of what you select even if it is on automatic. Rear AC works fine. Anyone have any ideas?

    klbutle1,
    I apologize for your concerns. Have you spoke with your dealer? If you would like to send me your VIN I will look into recall information for you. I look forward to your response. Have a great weekend!

    I have had problems with my A/C since March of 2010 and it is now June of 2011. I recently received a letter from GM concerning this problem. The letter is a special letter concerning the HVAC system, the interface module, the blower motor resistor, and a few other electrical devices connected to the blower controls of the vehicle. This is not a recall as specified by GM. It only affects some 2003 year model Tahoes. Your vehicle must be in this category for it to qualify. I had problems with the controls turning the air on period! I took it to a local mechanic to have it checked to see what the problem was and the mechanic told me it was the interface module that controlled the air being turned on or off. He replaced a fuse and told me that it would run temporarily on 1,2,3, or 5, but would blow a fuse if it was turned to 4. At this time I had a 3 month old baby and knew that it would soon be hot. I was currently unemployed and my husband was the only one providing an income at that time. We had no extra money to have the vehicle fixed. Under the conditions of the letter it stated that the vehicle had to be under 150,000 miles or within a 10yr period, whichever came first. As most people would have more than 150,00 miles on a 2003 vehicle by this time especially if it has been driven. This specific Tahoe has 172,250 miles on it. After having the blower motor resistor replaced in April 2010, the a/c was in working condition for a temporary time period. We still have been unable to have the interface module replaced due to lack of funds. I have been unemployed since 2008 and have not found work yet, where I live. Jobs are scarce and it is hard with a family of 5 to take care of these unexpected type of issues when they occur. The A/C blower only works on 5 now and this has recently occurred. I spoke with GM Customer Care Assistance and they provided me with a case# and said that they would look into this further. I was told they would call the local dealership that I had chose to have the vehicle worked on if they decided to cover. They told me that they would call between 1 and 2pm that day to let me know what they decided. I never received a call back concerning the issue until the next day. Then I was told that it would take a little longer to come up with a decision. They called back later the same day to let me know that their decision was that they were not going to do anything about it. My vehicle was out of the mile range but was still under the 10 year time frame. I don't think that it is fair that they are not covering a problem that was a manufacturing defect and that there was an issue with this on many vehicles or otherwise they would have never sent a letter out concerning this problem. I know that GM can't fix every problem that occurs, but this is about a $172.00 part that I am going to have to replace if I have the extra money, and when I have the extra money. I was so hoping that since it was close to 150,000 miles that they would go ahead and fix it anyway out of common courtesy, but not too many companies know what that is anymore. Everything concerns the almighty dollar. Oh well so much for getting my A/C fixed!!!!!!
