Hi there everyone I have a couple questions I hope someone could answer.
1 Does the heater use the AC for any function?
2 Will the AC function in cold temps?
I live in Iowa and it’s getting colder. When I got in the car this past Sunday I clicked the Auto button for the climate control. This is the main switch I use. When it came on I noticed that the air condition light was also on even though I had the heat set at 90 to warm the car. The heater seemed to work fine even though it said AC. I thought this strange so I hit the AC button and turned it off. The outside temp was upper 30’s. Today I get in the car and hit the auto button and noticed the AC light blinked three times and went out. Touching the ac button again gave the same outcome. Outside temp was 32 and dropped to 28 during my drive. The heat seems to work fine. When switching to defrost it continues to blow hot air. I did not try switching to vent or floor as I was preoccupied with the importance of my trip.
My wife is the daily driver of the Buick and I swear every time I get in it I notice some new issue. It’s funny yet not as our warranty is long expired. We’ve never had a problem with heat or AC. Was the light flashing because it was too cold for the AC function? Should I be worried about an issue arising? Is this a possible blend door issue? Any info or advice is greatly appreciated.
