![]() Today Called Greenwood Chevrolet and guess what, That recall is closed and have to pay out of my pocket I was told, no warranty for the last repair on recall. ![]() Now as of Yesterday SeptemI HAVE NO HEAT AGAIN, BLOWING COLD AIR. Well according to their paper work they replaced a sleeve part 22912580. Special Policy #11135, T5863, said may also need actuator. Searched for a recall, found one, printed and called the dealer. Well guess what, found a recall 2016 that a lot of people had problems with blowing cold air. I would have to wait 20 minutes to have the full effect of heat and defrosters in Winter, but hey "IT'S WORKING AS DESIGNED". There response to my complaint that they wrote on my sheet for Heat was "working as designed" What a joke, Sometimes it took a while for heat to come on, Had the car back at Dealer on November 16th for numerous problems, I typed out a sheet day by day with issues and gave to them. Lots of issues and money put into this car for the first few years but this report is about the heating system. Looks like the old girl is going to get put out to pasture. Basically, the repair bill would be somewhere in the $6-8k range. I guess the good news is they might be able to save the radiator by using a good solvent flush to remove the oil residue. And all associated parts of the coolant system (hoses, waterpump). The engine is leaking oil into the coolant, and based on two different independent mechanic opinions, the only remedy at this point is to replace the engine. Update from : So I finally got to a mechanic to have them flush the heater core, but the news got worse. I'll update when I get an official diagnosis and or fix. They did offer me some hope in that if it is heater core being clogged, I could try a $100 back flush of the heater core itself, and that might clear it for a season or two. They suggested I take it to the dealer for official diagnosis by them, but regardless of whether it is the blower door or heater core, the labor is going to push the job right into the $1200-1500 range. It was their opinion that GM made a bad choice in their coolant and it has resulted in many cases of gummed, clogged, or corroded cooling system components. I took it to my mechanic, and they said that in my case, they think the blower door is actually ok (they can hear it shifting when the dials are changed, but they suspect a gummed up heater core. Basically, if I put the system on recirculate, and the fan on low, I get some noticeably warm air, but as soon as I turn up the fan or switch to defrost (and fresh air is drawn in) the air becomes cool to cold. Let me know what you find or if you have other questions.I've had my Equinox since about 55K miles (now it's at 168K), and just as the weather was turning colder this season, I found that the heater decided to start producing very meager heat. The attached pics correlate with the directions. ![]() Here are the directions specific to your vehicle. If you feel the blend door actuator is the problem, here is a link that shows in general how one is replaced: However, if the heat was working fine and then stopped, there is a good chance the blend air door is the issue. If only one heater gets hot and the other doesn't, then the coolant isn't flowing through the heater core. First, is the engine coolant full? Second, if you have the engine running and the heater on, do both heater core hoses get hot? If they do and the coolant is full, chances are the blend air door is the issue.

What I would suggest is to remove the actuator and then see if it moves when you change the temperature. The blend air door is what controls the air temp entering the vehicle. Based on your description, it sounds like the blend air door actuator is going bad.
