I have 60,000 miles on the Edge. Air conditioner is working fine. I literally turned on the heat today when I noticed it would only blow out cold air.

With heat turned on high, passenger side blows warm while driver's side, rear, and vent blow cool air. what could this be?

How much is hvac to repair

Drivers door always says ajar

started just all of a sudden while driving,
would disconnecting the battery and resetting the computer resolve the problem?

I feel this could wear out the condenser or fan more quickly if always starting out on high.

tried restarting but that did not help

What is possibly causing these problems and how can I resolve/fix it?

does the tire pressure alert go away as soon as the tire is at factory settings? 35 PSI in the front and rear. alert was on when I got an oil change and it was on when I left. I asked about it and was told that Ford models need to be driven for about a mile before it goes away. it's still on. planning on going back tomorrow because they are closed. Just looking for clarification. thanks in advance

When I turn the tempature control knob, it only blows cold air. The door that allows heat to enter is not opening. The heater core is working because the lines ar hot inside the glove box.
