New power window motor, make sure you grease ur tracks while you have the door apart. there found at most local parts stores or online and there pretty cheap. Figure bout an hr for the first time. pretty simple might have to drill factory rivits.

ANd if you want them to go faster, wire them up on a relay.

while ur lubing the rails make sure the pulleys are spinning freely. thats a major resistance for windows i found out from experience.

I had the same thing happen on a truck I had. Try replacing the switch, or hotwire it to get the window up.

Quick check is pull the connector off the window motor (inside the door) and see if it's getting voltage or not. If it is, the motor is bad.

Replacing the motor isn't bad but allow yourself a couple of hours if you have never done it before, simply because it can take some patience to fish the motor and regulator assembly in and out of the door and lined back up.

**Make sure you understand what needs to be done once you have the motor and regulator assembly out of the truck. You have to bolt the regulator together to hold it because it's spring loaded, and if you simply unbolt the motor without doing this it releases all the tension and can cause serious injury**

Another helpful hint. I had trouble getting all of the bolt holes lined up when reinstalling the assembly. I found that by plugging the motor back in and slightly having it go up and down allowed me to get the holes lined up.....just be careful you don't have a finger in the way.

When mine started to give me trouble I just swapped in a manual window regulator. Work great now

Don't discount the switch either. It's a pretty simple piece in there, but I've had them fail. They can actually be "reconditioned" pretty easily if you like.

Need to find out why they aren't moving very well in the first place too. The design is obviously not real good, but since I don't have an NOS power window truck laying around, I have no idea what "normal" is speed-wise for them.
