I just spent quite a bit of time trying to figure out why my right front and left rear windows roll down fine, but don't like to roll up. It's not that they're going slowly (although they do) but that it doesn't seem to be getting power in that direction.

For example... I roll my passenger window down all the way or part of the way, but when I push the switch to the up position, the motor won't even try to move. Suddenly out of nowhere, while holding the switch, it'll move a little bit, then stop again. If I'm lucky, it will keep trying to work until it goes up all the way, but a lot of times it hasn't, and I could hold the switch all day without the window moving. I had the most trouble with it when it was cold outside. Using both the driver door switch and the switch on the door with the problem produces the same results.

I found the fix to be in the driver door switch thingy. Either the harness connector was dirty and unplugging it and plugging it back in would have worked... or cleaning inside the switch for the problem window fixed it.

What I found was that the contacts inside the switch had built up a gummy black substance (carbon?) that was starting to block the flow of current through the switch.

I'm not sure if there are differences between years, but so you are aware, my car is a 1986 LX-i Sedan. Here's what you have to do:

1. Take off the driver door panel
2. Disconnect any wire harnesses connecting the door to the door panel.
3. Take off the arm rest by removing the 6 screws on backside of door panel
4. There are 4 screws holding in the driver door power window switch, 2 are hidden. Here's the switch assembly after being taken out of the arm rest.

5. Now there are 2 screws holding in each seperate power window switch

6. After removing the switch from the assembly, hold down the top of the switch to keep it from jumping away (spring loaded), and remove the pin holding it in.

7. The rest is pretty self explanitory... just take out the 2 metal pieces, clean them up, and clean where those metal pieces touched metal inside of the switch

8. Put it all back together.

The motor should now work just fine in both directions! Enjoy!

Edit: btw, the driver window switch is made a little differently and is a little more complicated, but isn't too hard to figure out, but it works with sliding contacts so I couldn't imagine many problems with it.

Good write up.:) You should also use a little electrical contact grease (that's what the gummy stuff was) on the contacts to prolong their life, otherwise you might be pulling it apart later.

Just need some dielectric grease on them contacts to minimize corrosion.

The dude above said that too.

Normally I'd agree with both of you, but I'm giving the car away to someone who doesn't take care of cars anyway (I'm getting a better car in trade), so I don't care when the windows stop working again.
