Re: passenger window will not go up or down
Most likely the metal wire that is bunched up is the cable that pulls the window up or down. I know on other ford products that there are no parts to repair the window regulator and the fix is to replace the whole window regulator. Some window regulators come with the motor, others do not.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Hi donna , can you hear the motor running ,or no ? The window regulator is cables an plastic pulley's The cables fray an wrap around the inside ! You can test for voltage at the motor with a volt meter . That's better then guessing an spending money you don't have ! Hook black voltmeter led to a good ground , metal on the body . Take red led an touch to the wires at the motor one at a time while pushing the window switch ! If there is voltage an window is not working it's the regulator ! If there is no voltage go to the switch an check both sides ! Regulator or the switch is bad !
if you hot wired it straight to the motor and it works up and down fine chances are you have a broken or shorted wire between the button switch and the motor itself possibly between where the door opens and shuts at the hinge
The master switch is the one located on the drivers side. If this switch has a malfunction it can rob power from the passenger side causing the problem you have. If the regulator/motor are in working order and you know the passenger switch is ok then that could be the problem. Another couple of possible problems could be a broken wire in the harness traveling from the car to the door (inside the rubber protective boot or a weak window motor (1990 is pretty old for a motor of that type.
my passenger window would only go up. Found broken white wire in the harness on the Driver side .I slit the rubber boot carefully to expose all the wires, It stuck out like a sore thumb.The broken white wire was bigger than most of the other wires going thru the harness. Spliced back together now it all works fine
There could be a lock controller somewhere that is not working. I don't have a wiring diagram for your truck.
Generally, the power window motors are grounded thru the doors, or the switches provide ground. In your case the motors are probably grounded thru the doors. The master switch "overrides" the door switch so you have extra wires that do the same thing. The E wire probably gives the door switch power and the A and C are up and down. The B and D are override circuits from the master that bypass the door switch. Sometimes the motor is grounded thru the switch then thru the door.
I have the exact same problem on a Jeep Grand Cherokee 2004. The rear passenger window rolls down only from the rear passenger window and won't go up or down from the front. It has to be in the wiring because the problem was intermittent initially and a new window motor does the exact same thing. If you figured it out or have the wiring diagram please let me know.
It will be in the switch lift up the controls on both the drivers side and passenger side the wires going into the connection wiggle then and the button at the same time if you get any movement then you have a broken wire if not use a test light hook one wire to some metal and the other to the wires if their is any power the light will come on, if no light then you probably have a broken wire. The passenger side power comes from the drivers side control. When you open the doors you will see a large black set of wiring harness in the door going into the side under the dash that is the wiring harness for all the power windows and door locks, open it and test those wires for power.
Your power window motor could be bad. Remove the door panel and check for power to the motor. Check for power up and down switch position ,One wire will have power going up,the other wire will have power going down. If you do the motor is bad.
