Ford 500 Limited a/c and heater malfunction?

Whenever I start my car during the day, the A/C comes on automatically and I can't shut it off for a few minutes. Likewise, at night, the heater comes on and it takes a few minutes before it allows me to shut it off.

I assume it's some climate control issue. Maybe I pushed a button on my dashboard?

Recently, when the air is on during these few minutes, the car occasionally lurches a bit. Not so that anyone watching from the outside would notice, but I feel it.

Any ideas what it could be?

We also have a 500 Limited - ours with the automatic temp control & driver/passenger settings. Ours dosen't behave as yours… I would suspect a vacuum leak among all the hoses in the controls. Try turning the system completely off when you park it - listen for vacuum leak when you shut off engine and likewise when you restart next time. I don't have a shop manual which I'm sure includes a diagnoses procedure. If it becomes a real problem - the dealer will be an expensive place to sort it out… Fortunately, most independent garages also have online repair programs.
