Pass. Side front window powers up only
 

Hello there everyone I have a 2003 f250 ext cab LB 6.0l diesel with 260,500mi
So last week I had rolled both front windows down and hit the road to work 45min trip and so I got a call and rolled them up to talk after the call was over I rolled them down. So when I got to work I rolled them up and at night I try to roll them both down to let out the heat and only my driver side went down so I hit the pass.side switch nothing I hit the driver side for the pass. And the light in the switch for the window on the pass side door went out.and didn't go down. So now I tried up and you can hear the motor trying to go up but only if you use the pass.side switch the driver side does nothing up..... So I replaced both switches as I though rain and snow and dirt got into them and killed them nothing changed I checked for power to the motor and it has 12.2v on the up and when it switches wires to spin the motor to go down I only get 4-6v on both wires. So I checked the door jams for broken wires nothing and I can use my power prob to roll the window up and down so I think the motor is ok on the window..

I really need help for I snow plow and I need to roll down the window to talk to my guy and clean the window and so on please I'll take any help for this I'm thinking for just crushing the door for the insure. Company to fix the rust and the window lol thanks guys :-jammin

Here's a diagram. You can see the voltage for the pass side originates on the driver's side. Check your voltages on the driver's side. Make sure not to take any readings to ground. I think you already know, there is no ground to most of the circuit, it switches the ground on the motor to make it go up or down.
