2003 Dakota power window on passenger side won't go down unless you keep wiggling the master switch on the drivers panel, then sometimes it will work and sometimes it won't. won't roll down on the passenger side at all but once you get it down from the master it will roll up from the passenger side. any help appreciated

 

There are really only two things to check on a power window -

1. The motor itself - or the regulator - Since the window will go down & up its probably OK
2. The switches - Sounds like you have a bad switch on the passenger side & a loose wire on the drivers side.

I guess the wires could be a third - but lets check the easy stuff first.

Try removing the door panel on both sides & check for broken plugs at the switch. To verify the switch is bad you can use a jumper wire to close the loop on the harness the same as if you pushed the switch.

If it works with the jumper - replace the switch - if not - start looking at the wires. You may have a pinched wire where it passes through the door henge.

 

Bad window regulators are a known common Dodge/Chrysler problem. I used to replace 5 or 6 regulators a week when I worked at the Chrysler-Jeep dealership in Tampa. Here's an easy test: With the ignition on and the window in the up position, smack the flat area on the door panel above the map pocket with your hand. Hit it hard but not too hard. Use either switch and if the window works after that, the motor is bad.

I have heard and read of others removing the power window switches and opening them up and spraying electrical contact cleaner into the switch and it worked after that. You can also clean the contacts on the switch where the wire harness plugs in. CRC makes a good contact cleaner, you can buy a can at any good auto parts store like Napa, Carquest, etc.

I would say clean the switches first, that is the cheapest thing to try. You can also test the switches like Midget said. But you may find that you have a bad motor and/or regulator. If so, the dealer is the best place to buy the new parts. Dodge only sells the motor and regulator as an assembly, they do not sell a regulator by itself. I have heard that Advance sells the Dorman brand of aftermarket regulators and motors. I don't know how good they are, but I do know you can remove the motor from the regulator and bolt on a new one if the motor is bad. If you get into the door and the regulator is still good, all in one piece, you might try just an aftermarket motor or maybe get one from a junk yard.

Let us know how it turns out.
