The heater has a couple of actuators that move the air to the designated area. They either are stuck or don't get power or are not working. They are on the passenger side of the car under the dash. The drivers door has a module under the switches. You'll have to check your fuses and relays first then check the fuses to see what is sending power or not. It can also be a bcm (body control module)

Have checked all the fuses that I could find. Under the hood, by the brake pedal and by the drivers door. No luck. Any inline fuses?

On the left side of the dash there are 2 fuses and a circuit breaker that go for that door and module. You'll have to check those as well. One is a10A fuse the other is 15A and circuit breaker is 25a.

Checked all that and swapped out the breaker to other ones? Is there any way to jump out the switch just to get the window just to roll up? Maybe just run a lead from the battery to one of the wires going to the window motor? I was in auto zone looking at a chiltons and I think it said the dark blue was the up. But I don't want to hurt anything else. Thanks for your help

You should really let a pro do this as you don't want to screw something up as well as diagnose what the problem really is. If it's a simple reprogramming then it would be fixed and you wouldn't have anything to worry about.
