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.

I have a 2006 Equinox with a heat problem. After an extensive internet search, I find that this is a common but EXPENSIVE problem caused by a broken blend door. Chevrolet is not doing a recall for this issue and taking is not responsibility for their mistake. This is a safety hazard in a cold climate when the windows don't defrost. It is also a personal safety issue when a driver gets frostbite driving to work.

I had the thermostat replaced and had the coolant flushed 2 different times (3 months apart). Still making payments and had already replaced the calipers due to them sticking and I had to replace the carrier bearing.

Equinox LT V6

I have only had this car for about 2 years, and one day the heat worked and one day it did not.

I live in Wisconsin and the weather here is pretty unpredictable, but what is predictable is that it is going to be cold during the winter.

I have 2 young children that need to be able to keep warm while in the car on the way to school, to the grocery store, lets just say anywhere. Is that too much to ask, to have a car that is dependable and functions properly.

I was told by my mechanic that this fix can range from 1000 - 3000 dollars to fix and that even if it is fixed, this issue could happen again as this is a manufacturing error and it is a known issue with this car.

I am furious and stressed and upset. I always thought Chevy's are good dependable cars, I even owned a Chevy 12 years ago, and did not have these issues. I guess Chevy doesn't make their cars like they used to nor care about their customers purchasing and driving these cars.

Because this is a know issue, this faulty part should be recalled, replaced with better material, (not plastic), and paid for to get fixed.

Very very unhappy.

Equinox LX V6

  • Automatic transmission

When I bought my 2006 Equinox I had a problem with the heater, which was the heater switch. Cost me $750 to fix. The dealer (Chuck Graves) would not repair even though I had just purchases the Program Car. This to me was something they should have proved out before selling the SUV. I am quite sure they did not repair because of the cost . They wanted to charge me $1000.00 to repair.

Today, five years later I am having the exact same problem. My car was heating and then just cuts off and starts to blow cold air. This is a safety hazard, it is 21 degrees today and supposed to snow tomorrow. I need my heat and my defrost. I have to drive 48 miles a day to work. I am single so I have no one to depend on but myself. I have read so many complaints about the Equinox heating problems and now this has hit me twice. I lost my job last year and have taken a job where I have to drive 48 miles a day making 1/2 my salary from previous job. I do not have $1,000.00 to fix! I feel Chevrolet should be responsible for repairing something that cost so much to repair because of the design of this SUV. The entire dash has to be removed to replace one little plastic part (which is not worth a crap and a part which breaks easily).

I will never purchase another Chevrolet.

Seriously the worst vehicle I have ever owned. It looks fantastic and everything but when something starts to break get the Vaseline ready! This heater issue is THE WORST for me! We live in MI and if it would have happened in the summer I wouldn't have cared as much!

I live in Ohio and I need heat. Shouldn't have to pay someone $1,000 to fix this little plastic piece. Sometimes I am forced to drive and can barely see out of my windshield. Lets not wait until somebody gets hurt to fix this problem.

Well apparently I am not the only one that has an Equinox heat issue. A cheap piece of plastic can cause such a huge problem, especially with taking apart the entire dash. Seems like Chevy just thinks we will have the cheapest piece of plastic begind the most time consuming job by taking off the entire dash. Get this thing figured out or recal this issue.

Equinox LT 3.4L V6

  • Automatic transmission
  • 110,000 miles


I need heat! I live in Wisconsin where the temperature reaches between 20 degrees below zero to 40 degrees below zero. From what I have read once replaced, and the repair is estimated at $1000.00, it can break again due to a defect. This makes me angry that Chevrolet made this vehicle and due to the numerous complaints did nothing to fix the problem or even warn people!!!!

I have a 7 year old disable son who has problems regulating his temperature. My Equinox only blows out cool air when the heat is on and the A/C works fine. In the summer time it's not such a hassle, but in the winter I cannot take my son anywhere as he will freeze to death. We live in New England and the winter is frigid and you can get frostbite with in 10 min of being outside on some days. I cannot afford the costly repair of the heater core as I am the only one in my household of 3 that can work. My husband is also disabled and has severe spinal issues so my income must support all of us. Their medical bills alone outweigh my income, so having to pay for a part that should be recalled is not even remotely a bill that I can cover.

So here is what happened..... last winter (2014) the heat would work and then stop, sometimes I would get heat and other times not so much. Then in March we decided to take a trip to Myrtle Beach to stay with some family. On the 17 hour trip home the heat stopped... none, no warmth at all. My son was in his car seat in the back freezing. We had to stop and buy him blankets to try to keep him warm and my husband or myself had to sit with him to cuddle him, so his temp wouldn't drop. DO YOU, CHEVY, HAVE ANY IDEA HOW HARD IT IS TO KEEP A 7 YEAR OLDS BODY TEMP AT 98 DEGREES..... FIX THIS PROBLEM!!!

My wife's heater blend door broke, just like all of the other complaints, at about 60,000 miles. GM / Chevy wont replace it because its NOT a safety concern??? Really??? So if my wife's windshield is frozen over, I guess its ok to drive the kids to school then her to work.

My dad used to warn me about buying a Ford or anything American Motors....I might have to forget that advice and tell my four boys NOT to buy a Chevy. This is ridiculous!!!!

...and now...MORE problems with this vehicle!!!!!

I just currently bought this Equinox 2006 and on the way home of 15 miles the heat was blowing lukewarm air, everything else seems to work properly, even the heated seats work fine, just no hot air from the heat setting. I live in a cold climate, this is not cool. Is there a recall for this?

I bought myself a "nice" used vehicle that had only had one owner, a 2006 Chevy Equinox, thinking this would be a nice reliable mode of transportation, even in the frigid winters we have in Northern Michigan. The heat was not blowing much if any warm air, but was guessing it was likely an easy/inexpensive fix at around $100 or so dollars.

I do some research to see what could be the issue and how to fix it and see that this is a consistent issue with this year and type of vehicle. Not only that, but the research also told me it was NOT so simple to fix and definitely NOT inexpensive. Now I am stuck with this vehicle as my only mode of transportation to get to and from work in an area that has closed down schools for nearly the entire week last week due to subzero temperatures!!!! If this is an issue that is prevalent to this type of vehicle across the board, I feel Chevrolet should have the responsibility of paying for the repairs/replacement of their shoddy parts on the vehicles they manufactured!!!

Please see/reference complaint under cooling system repair. The solution to the overheating also corrected the interior heating problem. Air pockets were in the radiator line as a result of a hair line leak in the head gasket. Sealant was used to stop leak, air pockets removed and now the car has interior heat and it is not overheating, leaving me stranded on the side of the road. Praise the Lord.

My Equinox is blowing cold air took it to the dealer again after having the blower motor, blower resistor and pigtail for resistor replaced.

What they said is I need the heater core flushed, coolant flush and thermostat the cost $535 after paying them to me what was wrong.

GM knows there is a problem with the heating system please this is not how you treat your customers.

I have had my Equinox for just over two years. Two months after I bought it the alternator went out in a snowstorm on the road, fortunately almost to my destination...could have been much worse.. I have not had any problem since, and I do love my 29 degree weather my heater has suddenly stopped working. Was fine when I parked back in and no heat. Blower works....I checked the fuse..not the fuse...had two people suggest coolant....plenty of coolant, but mix was weak, so I paid to have the radiator flushed....not the problem...still no called for snow and sleet this morning and again Thursday. .I am scared to death that my wind sheild will ice over. It was suggested that it could be thermostat...only two bolts to remove, but was quoted $ best price $258.... Now I see that this is a known issue with the Equinox?? If they tell me it is going to cost over $500 I don't know what I will do.....pray for Spring to come soon? I have absolutely no faith in my dealership... Suggestions?

My heater just stopped blowing out hot air, I remember I was dropping the kids off at school and couldn't figure out why the car was not warming up. Living in Florida you wouldn't think it that important but we have some cold days (cold to us Floridians). I have to bring blankets for the kids to stay warm. I look like I belong up north driving to work. Gloves, heavy jacket, scarfs and a blanket on my lap. If you think about it, driving with a blanket on your lap isn't the safest. GM needs to get this issue fixed. It is definitely a safety issue, especially for those living up north and young and older people. After doing the research to how much it would cost to get fixed, I will have to leave it the way it is. I very seriously doubt I will ever by a Chevy vehicle again, especially if they don't get this fixed. My husband had to have the ignition problem fixed with out HHR.

Hey Chevy, how about quality more then quantity, we have loved one we want to keep safe!

Equinox LS 3.2L

  • Automatic transmission
  • 54,681 miles

After reading all the complaints about this heat/ac problem, I do not understand why GM has not posted a recall on this. In these sub-zero temperatures having a vehicle that won't even defrost a windshield is a major problem, not to mention there is absolutely no way to keep freezing rain off the windshield either. As a low income, single wage earner, I just do not have the dollars it will take to fix this problem. I originally paid to have the system flushed, not once but twice, 2 thermostat changes, and as I know now, it was wasted money as that had no effect on the problem. Isn't there some way to get this taken care of by GM. It seems this is a common problem with this vehicle. I have always owned a GM product, but I'm wondering if that's a good idea any more.
