By mistake, I forgot and put it down one day and have never been able to get it to go up since. Yesterday I tried trouble-shooting my power window situation and have made the following observations. 1. Was able to remove the driver side switches, take them apart and clean them all. I noticed that there was a lot of metal degradation in the contacts for the passenger side window. All contacts were cleaned. 2. Was unable to remove the passenger side switches to check for dirt and degradation (it seems you almost need to break the switch and the console to get it out?) 3. Used a continuity electrical meter to check for signals and wiring: checking from the passenger side door switch, when depressing the driver side passenger window up (light goes on), down (light does not go on). Very strange since the problem was the window would not go up. When depressing the passenger side window up (light goes on), down (light goes on). Also weird, since the window would not go up. 4. Removed passenger side door panel to check the motor. Powered the passenger window motor manually (with truck battery) and not a sound was heard. Does this indicate my motor has failed completely? Originally, the problem was that the window would only go down and not up, but when applying direct battery power I can't make the motor do anything, not go down, not even make a sound? I'm not sure what to conclude from all of these symptoms. Also - if the passenger side motor really is pooched, is it difficult to install a new one? It seems like really tight quarters in and around the door? Thanks so much, in advance! Laura and Chris

Like over the door and on both sides of glass to hold it up. Be sure to tape it a bunch of times, don't want it to fall down. Then there are clamps that clamp to the bottom of the window in the hollow part if the door. You'll need to loosen these so you can remove it from the glass. Then there are four bolts that hold in a regulator. Remove them and unplug the pigtail and remove the regulator. You'll have to collapse it slightly. It's made of cables and pulleys, you'll want to try to squeeze it together till it will fit through the whole in the. Install is just the reverse. You'll want power up the regulator till the clamps are on the glass and you can tighten them down. I suggest buying a new regulator first and looking at it so you can see what to remove in the door. I think I have an old write up somewhere where I installed power windows in my old truck. I'll try to dig it up for you.
