Cabin temperature regulation

I would be happy to look into this for you with your VIN. Please feel free to contact me privately. Thank you in advance.

My 99 Buick had the auto heat/ac controls which worked fine for the first 85K miles then after $4000 in ac fixes in the next two years,the Buick was traded away. Next car has manual controls.

Never again with all those auto controls.

My wife gets cold and closes her vents...then it blows more air onto me....making me colder...I tell her to leave the vent open and tell me when she gets cold.

HA - ...I didn't know my husband was posting on here!

My wife has the same problem, she can never get the temperature to a comfortable setting. She always claims it's broken. I have found that it is a pretty sensitive system. It seems to work very closely with the exterior temperature. I would suggest making minor changes to the temperature control knob each time. Try going up or down by only 1 degree each time until you find a comfortable setting. Also remember that the setting that works today may not work tomorrow because of the potential change in the exterior temperature.

I have the same problem. Thought it was me but I'm constantly moving it up or down. I manually shut the A/C off, assuming it was occasionally running to balance things. Helped, somewhat but still not resolved.

I don't think there's any good answer, but the way it works the best for me is to manually shut the A/C off, and once the car is warmed up I set the temperature at 75 or 76 degrees and turn the blower speed as low as possible and still be able to keep it comfortable.
