What stands out
Visibility accounts for 34% of every owner complaint on file for this vehicle — the dominant problem area across 12 categories tracked.
Owners have filed 236 visibility complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering visibility on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This Preliminary information communicates to the technician the need to inspect the induction system for potential icing issues in very cold ambient temperatures. To allow the ice to melt so that it can be drained from the related components. That any of the listed DTC's may set with or without poor engine performance.

The failure pattern owners describe
The heating system in the 2006 Equinox fails catastrophically when the plastic air blend door (also called the temperature blend door or heater blend door) breaks. Owners report that the heater suddenly blows only cold air, regardless of the temperature setting, and the defroster becomes useless. This happens without warning and typically occurs between 26,000 and 75,000 miles, though most failures cluster around the 40,000–56,000-mile range after 2–4 years of ownership.
The broken blend door prevents heated air from flowing into the cabin. With no heat to defrost the windshield, ice and fog build up, creating dangerous visibility loss in winter or rainy conditions. Owners describe having to drive with windows down in freezing weather, manually wipe windshields while moving, or pull over constantly—all while trying to keep children warm.
Repair is expensive and invasive: the entire dashboard, instrument panel, and sometimes the steering column must be removed, taking 7–10+ hours of labor. Costs range from $700 to $1,800. The part itself costs only $50–$200, but labor dominates the bill. One dealer quoted $2,600 for labor alone. Owners report that GM initially replaced the plastic door with an identical plastic part (with only a 12-month warranty), even though GM redesigned the same component as metal for 2010 Equinoxes.
Multiple owners cite online forums and dealership technicians confirming this is a "known issue" affecting a very large percentage of 2006 Equinoxes. GM has refused to issue a recall, claiming the problem is not safety-related—contradicting owners' experience that loss of defrosting is a major visibility hazard in winter driving. A Technical Service Bulletin from June 2012 covers repairs at no charge, but only for vehicles within 120,000 miles or 10 years of original placement in service.

Failure modes owners describe
Heater/Defroster Inoperability Due to Air Blend Door Failure
The plastic air blend door (also called temperature blend door or heater blend door) breaks or fractures, preventing heated air from flowing into the cabin. The door either stays in the cold position or becomes unresponsive to the temperature control actuator, causing only cold air to blow regardless of the heater setting. This renders both the heating and defrosting functions inoperative.
When: Typically between 26,000 and 75,000 miles; many reports indicate failure after 2–4 years of ownership. Some failures have occurred around 40,000–56,000 miles, though the problem can happen at any mileage.
Symptoms owners cite: Heater blows only cold air; Defroster does not blow hot air and fails to defrost windshield; Windows fog up and cannot be cleared; windshield ices or remains frosted; Clicking sound from dash area (in one report); Sudden failure without prior warning; Loss of all heating function while blower and A/C continue to operate
Repairs/costs cited: Repair requires removal of the entire dashboard/instrument panel and sometimes the steering column; reported labor ranges from 7 to 10+ hours. Part cost is stated as $50–$200 (plastic part with updated designs), but total repair costs range from $700–$1,800. One report cited a $1,145.08 repair; another $1,079.60. Dealers initially replaced the plastic part with identical plastic, though GM later redesigned the part as metal for later model years. Some owners report being quoted $2,600 for labor alone.
Recalls/TSBs owners mention: A recall was issued for 2010 Equinox models with the same defect (replaced plastic parts with metal). A Technical Service Bulletin (June 2012) was released covering repair at no charge for vehicles within 10 years of original placement in service or 120,000 miles, whichever comes first. One report mentions an extended warranty covering the actuator door defect to 120,000 miles or 1/1/2016, with GM offering to reimburse customers who paid out of pocket. GM has refused to issue a recall for 2006 models, claiming the issue is not safety-related, despite knowing of the problem. One dealership representative reportedly stated nearly 4 out of 5 2006 Equinoxes have this issue.
Secondary Water Intrusion and Corrosion
One narrative describes extensive water accumulation under the dashboard and carpet following a tropical storm, with water welling up from the floorboards and creating a musty interior environment. While this may be unrelated to the blend door failure, it occurred in a 2006 Equinox and suggests potential moisture management issues in the HVAC/dashboard assembly area.
When: Reported after tropical storm exposure; vehicle was parked with windows closed and seats remained dry.
Symptoms owners cite: Floorboards soaked from under dashboard to under rear seat; Water wells up when carpet is pressed; Musty odor in cabin; Damage to items stored on floor
Repairs/costs cited: Dealership repair and cleaning performed while vehicle was under warranty; specific repair costs not stated.
Recalls/TSBs owners mention: Vehicle was covered under warranty; repair forwarded to dealership.
Secondary Overheating (Possibly Related to Blend Door Failure)
One owner reported that shortly after the heating/blend door problem matured, the vehicle began overheating for no apparent reason, even after replacing the water pump, thermostat, and flushing the system. The owner suspects a relationship between the failed heating system and the overheating, though causation is not confirmed.
When: Overheating symptoms began shortly after heating problem developed.
Symptoms owners cite: Vehicle overheating without apparent cause; No resolution after thermostat replacement; No resolution after water pump replacement; No resolution after system flush
Repairs/costs cited: Water pump replaced; thermostat replaced; cooling system flushed. Costs not specified.

Heat began blowing only cold air, could not defrost windshield. Was on a trip with two small children. It became very cold and difficult to see; dangerous. Dealership diagnosis is a broken temperature control door actuator. Gm is so far unwilling to aid in repair cost. *tr
Tl* the contact owns a 2006 Chevrolet equinox. While driving approximately 55 MPH with the heating system activated, the heating system failed without warning. The vehicle was in the process of being inspected for the failure. The failure and current mileages were 69,986. The VIN was unavailable.
Our car 2006 equinox VIN [xxx] heater failed and defroster then did not work. December 5 my heater on this car failed to work causing dangerous conditions in my car as it was cold and defrost would not function. Window kept fogging over. Noted that there are multiple complaints on line about this. Reported this to Chevy. Part that determines heat vs cool fails, part costs about $38.22, Chevy…
At 46,000 miles heater blowing out cold air. Can't defrost windows. Problem started december 23, 2010. I have researched the problem and numerous equinox owners are having the same issue. Problem comes from the manufacture. Dealership is charging between $800-$1200. Entire dash board needs to be removed to switch out a plastic part that was placed instead of a metal one. *tr
In oct 2010 the heat stopped working on my 2006 Chevy equinox. At first I thought the problem might have been caused by air getting into the cooling system lines, because the coolant level in the reservoir had gotten a bit low. But adding coolant and trying to "burp" the system didn't fix the problem. Upon searching the web, I discovered that quite a few people had the same no-heat problem…
2006 equinox...heat blows out cold air..cannot defrost windshield which is a safety feature..HVAC fails to blow warm air..HVAC temperature door failed..this is only happening in 2006 equinox..many complaints on the 2006 equinox. *tr
Heater blows cold air in winter in chicago can't see while driving , very dangerous. *tr
A cheap plastic part (air temperature control door ) breaks and you lose all heat and cannot defrost or defog windows, and as such have virtually no visibilty, which in my opinion is a very serious safety concern. *tr
It just got cold in my region and I noticed my heater was not working. It just blows cold air out. I did some research and saw that there were lots of complaints about a heat blend door breaking in this model. The part costs approximately 30 dollars to buy but the associated labor is over $1200 dollars. Chevrolet hasn't recalled this even though it's kind of dangerous to not have a defroster in…
I have a 2006 Chevrolet equinox and the heater blows cold air causing the windshield to frost up. Took to a Chevrolet dealer and they said that it is a broken heater blend door and it cost me $1598.00 to fix. Chevrolet does not say that this is a safety hazard therefore will no issue a recall. I have been reading about this on other sites and there are some cases of people having to replace the…
