Chevy - Would not have guessed it

The vents on my daughters 2011 Malibu were stuck in the defrost position.

No trouble codes, checked on Internet, said to reboot computer, did it, now they work.

Would not have guessed that, but glad I do not have to tear into the dash.

Wife drives a 2004 Ford super crew truck and the air conditioner quit cooling on it, went on line for trouble shooting and a Ford forum site said it was not an uncommon occurrence and said to disconnect battery terminals and let it set for a few minutes. Reconnected terminals and A/C started cooling. Been a few years now with no reoccurance. Go figure.

I gave it about 1/2 hour with no power.

Defrost is the default, even on manual heaters. If something breaks or quits it is suppose to go the defrost.

Works wonders sometimes.

I shouldn't say this, but it works on computerized airplanes too.

David, when you say reboot computer do you mean disconnect battery?

My old 1995 GMC would flash check engine code when it was sub zero. The code came up as EGR. A mechanic said that was just a quirk with the truck, just remove the fuse to the ECM for about 20 minutes and it would wipe out the code. It may have only happened once a winter.

When I sold the truck, I told the buyer about it.

Seems like nearly all newer vehicles develop some sort of electronics issue sooner or later. Sad part is that totally mechanical heat/AC controls worked flawlessly for many, many years and were also much easier to use. Just give me a knob to turn or a lever to push.

I understand a lot of new vehicles have a totally electric hood release.

Haven't heard, yet, how you get the hood open to charge a dead battery???

Good question.

Yes, unhooked battery

We had a similar problem with an 2011 Buick Regal, took the fuse out for a minute and it fixed it!

uhooking battery or taking the fuse out for a while will clear most codes, in a hurry, disconnect battery and push on the brake, or anything that will drain the reserve power.
