Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Print this page Notes: The 2006 Equinox is plagued by a heating problem, as in the heater only blows cold air.

The reported cause of this problem is a small door, known as the air temperature blend door, which allows air to flow past the heater core. This door has a plastic connecting shaft to an electric motor and the shaft is prone to breaking after a few years. The problem has a typical repair cost of over $800.

The 2006 Equinox also has a number of reported problems ranging from the key getting stuck in the ignition, to failing speed sensors, and trouble starting the engine. All in all, this car sounds like one worth avoiding.

ABS activation at low speeds on dry pavement. This happens randomly and changes the vehicle breaking distance. It is also unknown how much it will change the distance. So it can potentially cause a low speed impact accident. This is due to not knowing where to break for proper stopping distance. Engine problem when starting vehicle. The vehicle turns over then stalls. Only way I have found to prevent it from happening is to press the gas pedal while turning it over. Wiper issue. My passenger side windshield wiper doesn't work. I live in an area where heavy snow fall happens. This is a danger to myself and others on the road. If my vehicle is on the road during a blizzard or heavy snow visibility is lost on half my windshield.

The contact owns a 2006 Chevrolet Equinox. The contact stated that there was an intermittent electrical short in which the vent controls failed to work for heat or cold air. The vehicle was not included in NHTSA campaign number: 09V489000 (visibility). The vehicle was taken to an independent mechanic. The technician replaced the motor blower, resistor, blower and pit tail; however, the failure recurred. The vehicle was taken to an authorized dealer for further inspection. The manufacturer was notified of the failure. The approximate failure mileage was 117,480.

The heating system suddenly failed and blows cold air affecting the vehicles windshield defrosting ability. This is a manufacturer's defect. The problem impacts the ability of the car to defrost. As noted in a letter from GM's director of product investigations and safety to the NHTSA on December 23, 2009, the 2010 Equinox was recalled since a manufacturer"S defect resulted in non-operational defrost systems that was a safety concern, could result in a crash, and violated Federal Motor Vehicle Safety Standard 103. In other words, GM has admitted on another vehicle that manufacturer"S defects that cause in-operable defrost systems are their responsibility to replace. Chevrolet Equinox drivers are at stake. Not having the ability to defrost your windshield could lead to traffic accidents vehicle damage, injury and possible death. I am requesting the NHTSA to investigate this and order GM to replace the defected part / parts and refund repair cost to those of us who have or will have to pay for these expensive repairs.

Heater and defroster are not working. Blower works great but in the winter cold air does not defrost windshield. There is no warm air at all. This makes driving conditions very difficult in the cold weather. My wife depends on this car to get to work every day. I understand that the issue is a part that costs abaut $65 but the labor cost is abaut $1000 we cannot afford to pay that. Chevrolet should step up and put a recall on for this issue.

Heater / defrost system stopped working. Only blowing cold air. Live in Idaho and temperatures get below zero. No way to defrost windshield causing a safety hazard. Chevy dealership quoted repair of the heater vent door actuator at $1200, since the entire dash board needs to be removed. History shows several issues with door actuator malfunction.

Equinox 6-cyl

  • 118,000 miles


Failure of the HVAC blend door [1] has made defrosting the forward windshield in cold temperatures impossible. This is a safety issue because of the limiting of visibility and in violation of standard 103 [2] from the U.S. department of transportation. GM has admitted a design flaw in the HVAC blend door actuator in that a dealer replacement uses an updated HVAC blend door actuator which more accurately limits the rotational travel. The failure of the HVAC blend door occurs because the original faulty designed HVAC blend door actuator travels too far causing structural stress on the blend door which eventually leads to premature failure of the blend door. This results in vent air not passing over the heat core, therefore making defrosting of the windshield not possible in cold conditions.

Temp door actuator broke leaving me without heat to defrost windows. Repair cost of door $50 cost of labor $1200. The door is made of cheap plastic but the entire firewall must be remove to replace part. Then my engine blew 1 year later. Cost $1700. Now my engine blew again.

The heater vent door has become inoperable resulting in no heat entering the cabin. I understand this is happening to many other people but yet no recalls have been issued by GM (only service bulletins). This is a flawed design and is a hazardous safety issue during an ice/snow event. The vehicle also began overheating for no apparent reason (even after replacing the water pump, thermostat & flushing the system). These symptoms all began shortly after the heating problem matured. Related or not, there are many other people out there that are experiencing similar problems with similar (major) expense in trying to resolve the issue(s). There is something flawed in the design of this coolant/heating system and GM should be held accountable!!

The heater started blowing cold air while driving not allowing the windshield to defrost and limiting visibility. I had to pull over multiple times to wipe windshield down to see so I could get home. Nearly caused an accident.

The blend door broke and was replaced for only $50 due to carmax dealer warranty. Now my car has 115K miles on it and the heater is blowing cold air again. I believe it's the same problem, a broken blend door. I can't believe I have to replace it again! this needs to be addressed. This is a huge safety issue that needs to be recalled.

Heater stopped blowing hot air. After diagnosis by certified technician I was informed that the actuator for the heater blend door is not working properly/damaged. After researching the issue it became clear that there have been several hundred safety complaints filed in regards to this issue. A resolution needs to be attained as the repair cost for this item is around $1000. A recall needs to be issued by GM since it becomes a safety issue when the inability to defrost your windshield is not there.

There is 241 safety complaints on the heater blend door! the blend door on the 2006 Equinox is defective creating a serious safety hazard to the vehicle occupants and any one else one the road. The blend door actuator rotates to far causing the blend door to break. This does not happen over a short period but over a longer time frame. This is a very serious safety issues especially when it gets cold. The windshield will freeze up and with no heat the driver and passengers could get frost bite. The NHTSA needs to issues a safety recall now before someone gets hurt or killed. What is the NHTSA doing about this if anything?

My heater quit blowing hot air and thus, the windows fog up. I took it to a mechanic and it is the blend door. Upon further reading of this problem, I have found that many 2006 Equinox have the same problem. It is a 10 hour labor job and so $1000 to replace. Since this effects visibility, I feel it is a safety issue.

Faulty temperature blend door. No heat resulting in no defrost or defogger. Major problem when living in the midwest in the cold and wet season. You (GM) should be responsible for the plastic piece being replaced, not the consumer. This should also be a recall issue due to the safety issues that result from this problem.

No warm air from defroster heater. Thermostat replaced, problem not solved. Mechanic told me heater door blend door broken. No recalls, even though common problem. 2010 Equinox reported same problem and has recall. Approx $ 1000 repair and definite safety issue. GM should recall 2006 Equinox also.

Starting in December 2011, our heater blend door broke on our 2006 Chevrolet Equinox. It is a wide-spead issue with the exact make/model of this vehicle, effecting several hundred, if not thousands. Chevrolet has released a technical service bulletin may of 2012) with the exact issue, as well as re-designed the door for future fixes, but refuses to help repair the vehicle for me. Even know the problem started before the mileage factor in the warranty for the part, and is over the mileage now, GM refuses to help. My car has no heat at all, windshield does not de-frost, does not de-fog. My wife has to use this car to drop our autistic son at his school as well as to go to work, we can't have no heat.

While driving on a cold and rainy day, my windows began to get foggy. I turned on my defrost and my windows continued to get worse. I then notice it was blowing cold air I turned the knobs to see if I had it on air conditioning instead of defrost but it was on the correct setting. I became very afraid because I couldn't see out of my windshield! I had to keep wiping off the windshield with a towel just to get to work. I then I had to repeat the same process returning home. I researched the problem and found that this common in 2006 Chevy Equinox there is a plastic piece that breaks after constant use(heater blend door) and it will cause the defrost to only blow either cold or hot air. I was told it would cost 800-1000 to fix or more depending who fixes it. I am so afraid to drive this car in rainy weather and soon winter will arrive. GM should really replace this part before someone dies from a faulty piece of plastic.

  • 56,000 miles
There has been no actual incident. I am writing to inform you of the safety issue that the lack of heat and defrosting capabilities of the 2006 Chevy Equinox may cause. If the issue of the problem is not resolved there is a chance that a window will not be defrosted and the drivers view will be obstructed. There is also the health issue for not only the driver but any passengers in the vehicle. Not being warm or able to see and cause rising costs of both care and health care costs. Help push the issue to GMC and get the problems fixed at their cost.
