Passanger side window won't go down all the way

the passenger switch need to be replaced

Window regulator most likely but before changing it out take the door panel off and apply current to the contacts of the actualy regulator. If the window goes up then switch the contacts and now it will go down. If nothing then regulator (window motor) is bad. If it works then your master control switch for all the windows is going bad.

sounds like a bad switch, which is very common on the gm line of mini vans..

oftan times its the master controle switch on the driver side that allows the power for the passanger sid the other comman problem is the harnes in the door jam has a broken wire or more than one take the pannel off the kick pannle off unplug the harness at the kick pannel take the rubber loom cover between the door and the rig loose pull some wire through so you can see it and find the break and repair hoped this helped

Check the wires on the driver's door between the door and the post. A break in a wire will affect the passenger side.

You may have a broken track. You need to take the door apart and have a look behind the inside door handles.

You may have a broken wire that goes to the door from the main body. Take a look at the area where the hinges are. You will see a rubber boot. In that boot are wires that go to your door. One of them may be broke.

Even though you have new switches it is possible that on of them has gone bad and may need to be replaced again.

Good Luck

So you know the problem

Drivers side switch lowers the window
but doesn't raise it

driver's window goes down and have a hard time getting it to go back up

Remove the door panel, and use two jumper wires to the window motor. One wire goes to a good, non-painted surface on the metal body of the van, for a good ground. The other wire goes to a 12 volt source. Touch the two wires of the window motor with the two jumper wires.

Tries to go up? Switch the jumper wires around, and try again.

it is probably the motor in the window
