2006 Chevy Cobalt AC Problems

I had a irregular problem with the ac on a 2006 chevy cobalt. Only setting 1 worked right, then when i would switch to 2 or higher the air would still blow, but the ac compressor would turn off and i would only receive room temp air blowing on me. I found the problem was a connector on the back of the ac control unit was having i intermittent connection on one of its pins.
I temporarily fixed it by having the ac head unit plugged in and gently rotating it up side down 2 times. Which twisted the harness a little causing the connector to have pressure on it and forcing all the pins/holes in connectors to connect. I also made a make shift shim outta a plastic piece which i used to fill the little amount of clearance of free play the connector had when plugged in.

I'm having the exact same prb with my sons 2007 Chevy cobalt every time we take it for a ride we just say a little prayer that the AC will work, some days it works other days it does not. I'll be checking this part for sure now thanks for sharing!!

[@rizzler_chess]

You fixed it?

Thanks you, my man this helped me alot about my 2006 chevy cobalt.

[@lawselflowers7684]

I found the problem. If you remove the panel on the driver side near your right foot abd look under you will see two actuators. The one on the top controls moving air from vent, to defrost, to feet. The actuator on the bottom controls the blend door specifically for hot and cold air. After removing the bottom actuator, you may find as I did, that the long plastic rod that is part of that blend door, and connects to the hole on the actuator, is twisted and broken off. My fix for this was a vehicle rubber hose and crazy glue to reconnect both pieces. It was not easy but it worked and I didn't have to remove anything but the actuator.

[@jennifermurray5262]

I bought a 2006 Chevy cobalt LS from a soldier on Fort Bragg I have noticed that the lights do not light up at all I do not get any cold air and I’m not getting any hot air during the winter what is your suggestion to fix this issue?

[@sledheads6355]

When I turn my ac on my colbalt it drops down 1 rpm and the car runs extremely rough when it’s on any idea on what that could be? I am thinking mayeb the blower motor or it’s low on refrigerant but now sure

[@chrissmith8769]

I’ve got a 2009 Chevy cobalt. Only blows cold air and won’t blow any hot air. I’ve changed the thermostat and the blend door actuator on the passenger side and it still won’t work. Any ideas what it could be

[@JayDeCree]

okay so like my ac wont turn off at all even on 0 do i have to do something like this?

[@Kiryu]

So my issue is it works until I turn it to 4 then it shuts off, unless I push and hold it in HARD. Then it works, but the instant I let go it shuts off again. What do I do for this?

[@lawselflowers7684]

The problem I'm having is my cold to hot knob does not change the temperture. It works sometimes and sometimes not. it's either stuck on blowing cold air even when turnes to how, or stuck on blowing hot air even when turnes to cold and the ac is on. The bend door appears to be opeaning and closing just fine. Any help or tips on what to check for would be greatly appreciated.

[@danielchavez2157]

Im having the same issue with my cobalt it's stuck on heat actuator appears to be moving blend door to cold but stays hot. compressor is on and running I have a hunch the actuator internal gears might have failed

[@JesseC1007]

@@danielchavez2157 same with mine stuck on heat and summer is coming. Did you find out what the problem is thanks.

[@jamess7657]

The problem I'm having is the a/c runs when the knob is in the off position but shuts off when turned to 1, 2, 3, or 4. Also it blows like it's on 4. I have cold air.

[@MrJohnnyDistortion]

Thanks for the instructional. You should have experimented with the shim on all 4 sides until you found where it works best.

[@JerTin-Woodlands]

A/C was working before the alternator bit the dust. Installed used, now car whines when it hadn't before...and A/C doesn't blow cold. Lights light up, inside. Haven't tested relay, but red fuse looks okay. Just no cold air...but the whining is annoying too.

[@johnboothe6398]

The probkem Im having, is that the fan won't work. For a long time, it would work on 1 2 and 3, but not 4. Now it will only work on 1 2 3 sometimes. Also, the knob will turn, but doesn't feel right.

[@jorgewitte2410]

Thanks man! I got a HHR and gave the idea where is the chip!

[@alanwylie8960]

Back in the 70's I thought the Chevrolet Vega was cheaply built, these present day GM China Motors are far worse.

[@dgibson2917]

I was wondering about the fan knob itself. Mine is broken, do I just pull the knob off the vehicle at salvage yard, or do I need tools to take off the a/c fan speed knob?

[@danlynch6228]

For just the fan knob, you just need to pull the knob off. I used pliers to give me a firmer grip.

[@MrJohnnyDistortion]

The fan switch can be replaced from the back of the AC control unit. 2 screws. Remove the plastic trim, remove two screws holding the head in place, remove the two screws from the back and slowly lift out the switch and slide the new one in. Make certain that the knobs on both switches are on 0 and that nothing moves out of place.m

[@bryansanger5452]

My granddaughters 2006 Cobalt the blower speed switch turns on 1, 2 , 3 & 4. I don't notice significant difference in air movement between them. I don't hear any difference at all for the high 4 setting. What would you suggest could keep the 4 setting from blowing at high speed?

[@sledheads6355]

Could be your in cab filter it’s behind the glove box

[@bryansanger5452]

@@sledheads6355 that was it. Replaced a very dirty cabin air filter and the Cobalt cools down and we notice air velocity changes now. Thanks.

[@MrJohnnyDistortion]

My blower fan switch began acting up and stopped. All plugs to the blower, resistor and control heads showed power. Replaced the resistor and no change. Replaced the blower fan speed switch and again no change. Changed out the AC control head twice and still no AC blower. Any clues anyone?

My snowflake will not come on at all unless i jam my leg into the center console, painfully. Any slight movement away from tons of pressure and it will go off. I've had this issue for so many years, it's made me hate my car. The blower also only work on 3 and 4

[@ClickClack_Bam]

Yes you need a new switch relay I'll bet. Mine worked the exact same regardless of what setting it was on. You do NOT need to order an entire new face for the ac controller. You only need the new fuckin turning selector relay part that the dial plugs into. Here's the Amazon link. www.amazon.com/dp/B0026N32K4/ref=cm_sw_r_cp_apa_fab_0-3DFb7JHK853 Here's also the selector switch dial. Mine was cracked & needed this replaced too. My stupid gf after the air wouldn't work kept turning the dial thinking it would magically "turn on better" & broke the fuckin thing. Dial selector www.amazon.com/dp/B00Z7MWNZ6/ref=cm_sw_r_cp_apa_fab_3a4DFbCE3EGMN Hope this helps.

[@ClickClack_Bam]

Oh. If you buy a switch relay know that replacing it you'll need special screwdriver, the hex type, to remove the 2 screws that hold it in place once you remove the ac face control unit. If your dial isn't cracked just pull off the old dial & reuse it. -MAKE SURE you look in the hole to see you removed the metal "D" shaped dial from the stem piece that the dial pushes in to. It always gets stuck in there for me. This piece shores up the dial "D" shaped plastic hole in the turning dial. So when it turns that metal stops the dial stem from cracking the dial "D" shaped housing hole. Don't do this step & try using the dial without the D metal piece & you'll absolutely crack the dial housing hole & you won't be gluing that shit back together cause it's a perfect fit. I've tried super glue etc & it won't hold the pressure of turning the dial with just plastic (hence why they used the metal D supporter clip thing). This might sound confusing but when you get in there you'll see exactly wtf I'm referring to lol when you come across it all.

[@user-rj1vl2vx4r]

My problem is that the air conditioning is blowing just fine. It's that it won't change from window setting

[@LHTAS]

that resistor works with earth. the connector mentioned in the video of 2 cables, one black and one brown. There is no kiss to change it. I will upload a video for those who like earrings

[@anthonyarroyo2898]

Hey dude i love this video. But mines is a bit different, when i switch my knob to 1 2 3 or 4the compressor comes on but NO air comes out hot warm or cold. And sometimes i gotta touch the wires for the a.c. to start blowing. Help plz

[@GEARMOAUTO]

What wires? If no air comes out. Try turning your ac on with it on any number and smacking the bottom of your blower motor. If the motor comes on then it means you have a bad blower motor. Try that and let me know.

[@anthonyarroyo2898]

The wire harness that connects to the back of the AC knobs is what I touch and it comes on

[@GEARMOAUTO]

Did u try to manipulate the wires to a posistion that the ac stays working? Maybe u can twist the harness like in the video. I also have been shown sometimes the femal side of the connectors can widen and not contact the pins good. Is it the type of connector that you can adjust the pin holes to make them smaller? Let me know if im not on track but i belive these would be things u can check if im understanding correctly.

[@anthonyarroyo2898]

Yes i have manipulated the wires so it can work but the second i hit a pot hole or just the slightest movement then it cuts rite off

[@GEARMOAUTO]

Well man, maybe you can isolate the bad wire or the pin connection that is loose. I dont have anymore ideas for you. Let me know what you do though or if i can answer anymore questions.

[@mama21bella84]

I'm planning to buy one. Is a good idea or nop? A lot people told me is a bad car! That's true?

I would highly recommend not buying it. Get a TOYOTA OR HONDA

Hahaha br this made me think to hit the side of the unit and it WORKED! Just slapped the side of the panel and BOOM! Came right on. Smh

Sounds like a blower motor. Try hitting / slapping the bottom of the blower motor under the passanger dash area

My 2006 cobalt turns off when i turn the air on. I checked the fuses everything is ok.

[@GEARMOAUTO]

The whole car turns off?

[@GEARMOAUTO]

Or just the AC?

[@gabbanellitwotone3489]

Whole car

[@GEARMOAUTO]

Sounds like when the AC compressor turns on it is just enough load to kill the engine. Does it idle rough when the A/c is off? It could be the idle needs to be higher rpm / healthy idle. Maybe there is a vacuum leak or the throttle plate is really dirty causing a weak idle.

[@gabbanellitwotone3489]

No when i turn it off it turns right on. And when i put the heater on the the car shuts off too.

[@johnboothe6398]

Firgot to mention, its a 2006

[@liberalmike27]

For a while my 2005 Cobalt AC knob didn't blow on the 3rd setting--worked on the res, 1,2, and 4. Then it started working again, and has ever since. (short?). Mine has a weird problem--even when the AC is OFF, and you turn on the "recycle air" switch, it ALSO turns on the AC. None of my other cars ever did that. So if I just want to recycle air, if I get behind an oil-burner or something, I can't. I've always figured it was a wiring problem--now that I see this, I'm even more sure. Somehow my recycle button has been also wired into turning ON the AC.
