I have a 2007 HHR. A few days ago the air conditioning went half out. What I mean is that I get no cold air when I run the AC unless I turn on the recirculate button, then the AC runs like normal with plenty of cold air. I am not talking about a matter of degree. I literally get no cold air in the normal setting and very cold air in the recirculate.

I will call tomorrow for service, but I was wondering if the problem might be a blown fuze or something. I have looked at a couple of fuses but did not see anything.

Any suggestions?

Thanks

 

Does your engine coolant temp not read at all? By that I mean, when you start it up, does the needle not move from bottom?

 

The engine coolant temp gauge is working fine, either that or it is stuck, but it does not read zero.

 

But still, check the coolant level in the "jug". Evidently there is a small amount of evaporation that occurs over time leading to empty condition for those of us who did not USED to worry about coolant levels.

Also check that nobody messed with the knobs, temp & select. I'll bet the dealerships love to charge $79 to turn those knobs to the correct positions.

And, what Officer was getting at is that the "computer" will turn the AC off if it thinks the coolant level is low.

 

" what Officer was getting at is that the "computer" will turn the AC off if it thinks the coolant level is low."

And it would do that in either recirculate or outside air position. He's got a/c, but only in one position. Have you checked the cabin air filter, just to rule things out.

 

One thing to consider is maybe a jammed "blend" door up in the dash, and I can't remember if they are servo operated or vacuum operated to save my life. Another thing to consider is a possible failure of the selector assembly itself, no signal to the BCM, no operation of the blend door and the resulting condition of A/C only in recirculate.

 

First thing.Check to see if the compressor is engaging in both knob positions. If yes,then a probable blend door problem.If only in recirculate then could be a number of things as stated before.
Also,when checking comp.engagement,be sure temperature dial is turned to coolest setting.

 

Weirdly, it is now working. It first went out during a fourteen hour drive from Florida. It stayed out for the next several days, but now seems OK. I will keep an eye on it. Thanks for the help.

 

Dear Chriskline,

I have read your post about the air conditioning situation in your 2007 Chevrolet HHR. I can understand how frustrating this must be with the hot weather in on us.

I see your last post, yesterday evening states that your air conditioning is now working fine. If you would like assistance in the future making an appointment for this please get a hold of me.

Sincerely,
Michelle, Chevrolet Customer Service
