What would cause a 2000 ford windstar left power window not to go up and down?

Answer 1

3 things to look for

1. the door switch 2. broken wire between door and body 3. most likely the window motor has quit and will need to be replaced

Also try this!!!!

Stuck Armature BrushesMake sure the motor is in fact bad... Many times they just stop working because the armature brushes hang up and will not make contact with the motor armature. Sometimes you can slam the car door and this will jar the brushes and they will make contact with the armature. If this doesn't work you will need to remove the door panel and reach inside the door where the window motor is located and tap the electric motor with a small hammer or some other suitable object. While you are tapping the motor have someone hold the window switch in a functioning position, either up or down depending on the position of your window. I have done this many many times and hopefully it will work for you and you will not have to replace the motor. Good luck

This works great, just be careful when the window does start to move. Have whoever is tapping on the armature to remove their arm from the window path. I almost smashed my husband's hand!

I tried the armature brush thing. Worked great!! Thank you. I wasn't looking forward to replacing the motor.

I have a Ford Windstar 2003 and for the last one year either the front right or left power window has not been rolling down. AAA mechanics told me they have to strip the whole door so as to diagnose the problem which might cost up to $500 to fix. My car inspection was due this month and was not ready to spend that much. I came across your diagnosis and I tried it. First I did bang the door several times but didn't work and almost gave up. Then I switched on the car,closed the door,estimated the position of the armature and started banging the side of the door from the inside. Viola! within two minutes the window rolled down. Thanks for sharing you saved me a tone of money.
