Defogger Problems of GMC Envoy

Air conditioner quit working on level 5, would work on level 1-4, level 5 would keep turning off. Shortly after this within the same day I could smell something burning coming through the air vents. Mechanics noted and showed me that the resistor plugs on the back had burned and melted together, that's what was causing the burning smell. Needed a new resistor, pig tail, and blower. Also my fuel gauge and rpm are broke, have not been working for the past 3 years.

The problem with my 2006 GMC Envoy is everytime I turn the ac/heater on there is a foul odor emitting from the vents for approximately two to three minutes. I contacted GMC they state that the problem is occurring because I live in a high humidity area of the country and that a dryer needed to be added to the vehicle for 800 dollars and they could only offer to take half of the price. I stated to the representative that this is not on the vehicle that I broke that this problems seems to have developed somewhere in the design and development of the vehicle why should I have to take on the responsibility of repairing it when I purchased the vehicle brand new.

The contact owns a 2006 GMC Envoy denali. The contact stated that in October 2009, he noticed that the fuel gauge would "flutter" and register that it was empty when he added gasoline to the fuel tank. After consuming five to seven gallons of fuel, the fuel gauge would begin working normal until the it was time to add the maximum amount of fuel in the tank. The check engine light also illuminated and the heater would blow cold air on the driver side and hot air on the passenger side. The vehicle was taken to the dealer where the sending unit in the fuel tank was replaced and the heater was reprogrammed; however, the heater still did not function properly. The VIN was unavailable. The failure mileage was approximately 40,000. The current mileage was approximately 46,000.

2006 Envoy denali. Consumer writes states gas needle stopped functioning the consumer stated the gas needle began to fluctuate in the beginning and since that time, the needle has been stuck on empty, and the engine light illuminated as a result. In March of 2009, when the consumer stared the vehicle, it sounded as if there was something metal tumbling around under the hood. Upon inspection of the vehicle, it was determined the engine needed to be replaced. On June 10, 2010, the vehicle would not start and had to be towed to the dealer. An inspection revealed a starter was needed. Also, an alignment was done and the rear brake light was replaced. On June 12, 2010, the vehicle would not come out of park. After 25 minutes and over 50 attempts, it finally came out of park. The consumer drove to the dealer, but they were unable to find a problem. September 2010, the consumer noticed the rear of the truck was sitting very low. The rear end air suspension needed to be replaced. The air condition randomly worked.

I purchased a 2004 Envoy with 18,000 miles in the summer of 2006. Beginning in January 2007, my 3 year old son let me know that he was cold while riding in the back seat and begged that I turn off the air. Turns out that the vent in the back of the car was blowing ice cold air on my son. The temperature outside was approximately 10 degrees. I called and scheduled a time to take my car into the dealership, as it was still under warranty. I found out that the vehicle had a "bulletin" stating that GMC was familiar that there was heat failure in the back of the cars, but the company was choosing not to do a full recall. Instead, they were waiting for customers to discover the problem and bring it in for repair. They had to install a special pump, however, this still did not fix the problem. Instead, it just modified the temperature of the air from approximately 20 degrees to maybe 50 degrees. Not a lot of comfort in a minnesota winter. I was informed that bottom line, it was a design flaw with the vehicle, and that I could just try to force the air from the front of the car to the back seat. What is the point of having vents in the back of the car, and having a separate heating element specifically for the back of the car? I purchased this car because I thought that with the vents in the back, it would help heat the car faster in the winter, helping to keep my son warm. I do not believe that heat should be a luxury, and am disappointed that GMC would not do more to correct the problem. I want it to be known to the general public that this is a problem in the Envoy and trailblazer, especially for families with small children who do not have a voice to let their parents know the icy air blowing on them.

Since we have this vehicle the heating system fails to work properly. We have repeatedly had the dealer and a g. M. Representative try to repair this problem. After their attempts the system still doesn't operate correctly and now I am left with a defective air conditioning system that only works sometimes. I am hearing from other people that know who have this vehicle and the Chevrolet version the trailblazer that they have very similar problems. In the wrong circumstances not having heat/defroster working properly could be a safety hazard, yet this fails to become a recall or alert to drivers. As far as the a/c problems my son actually got heat stroke in the back of the car on a very hot day due to the fact that only vent windows open in this area and unless the vehicle is in motion it becomes very hot in the third row of seats in this vehicle if the air is not working correctly. G. M. Should fix these vehicles! I have reported my problems to the better business bureau and I am hoping to return this vehicle to g. M. Early. This car has also had numerous electrical problems with the radio. I feel that since they tried to fix the heater they have screwed up something else in the electric since they had to reground the whole system and this ground has already had to be reground due to the fact that it disengaged itself from the vehicle, doesn't sound like a safe repair to me.

Dampers located inside heater control system are very annoying. Driver can constantly hear shutter opening and closing as vehicle accelerates.
