Recently, a deer hit my car causing the driver's window to explode into the cab. Tiny bits of glass were everywhere.

A couple of days ago I tried using the air conditioner for the first time this year and the air is HOT HOT. I can't even change it to vent in outside air. It's as if it is stuck on high heat.

also, The contol **** doesn't turn all the way to the right (hot) it does turn all the way left (cool) but blows very hot at every setting.

Could pieces of glass that have fallen down the vents be causeing the "flapper" from opening and closing?
