I have a 2006 150 supercab 4X4 and the front passenger window seems to be extremely slow when it comes to rolling the windows up. If you rule it up by itself I guess you would say it is about half the speed as my driver window but then if you push up on both the driver and the passenger side it becomes EXTREMELY slow... has anyone else encountered this issue and if so what was the fix?

This sounds like a voltage thing. Get out a VOM and start checking Voltages. If you can get to it with out to much trouble check things out in the door. See if the lift motor is getting the proper voltage, if it is, hit the lift mechanism with your favorite lubricant and see if that improves thing it that doesn't do the trick the motor is bad. If the motor is not getting the proper voltage then start tracking the wiring back to where the Voltage is normal and fix what ever is causing the voltage drop.
