Only half of my power windows work

FSanchez · Mar 18, 2014

Hi folks. First actual thread so bear with me here. I have a 2000 Ford Taurus LX. It was a gift and it's been through it's share of mishaps. That aside, here's my dilemma. I believe it started when I unwisely left my driver's window down in a rain storm. Only for an hour or two, but moving on. The following day, my windows didn't work. Replaced the drivers window control, still the problem persisted. Looked in the grommet between the door and cab and found the main power wire, the blue wire, had split entirely and was no longer connected. Taped it back together and now only half the windows work using the drivers controls. When I use the live wire and connect it to the corresponding wires to make the windows rise and lower, they work perfectly, but it's becoming a nuisance. Would any of you happen to know what is causing this? Drivers side window goes down, won't go up. Passenger's side works fine. Rear driver's side works fine. Rear passenger's side wants to go up but won't come down.

First of all, do a proper wire repair and don't just tape things together. You may have to cut out and replace the section of wire that goes through the grommet.

Check all your fuses. You might have blown some with that loose wire.

Might I chime in with a pic.

Mine had more than one wire broken. When there is one, there will likely be more, even it the insulation is not broken fully.

Pic from my '01. In my case, the wire shown spliced is too short relative to the bundle and it pulled apart. I added a splice so it would be better, soft wire. I think there were 2 othes in this bundle that were broken but not really pulled apart. Windows and door locks. My door gets lots of use compared to most. Hope permanent fix. If not, I know where to look. Also broken wire in the wagon hatch accordian. That one killed the radio when in "R" and then killed the backup lights. Speaker wires shorted to the backup light wire.

I had the same problem with the driver's side window going down but not coming up. Turns out it's a GEM problem with the one-touch function.

If you are still having a problem with it even after properly splicing the wires back together, you may have to run a bypass. Information is below..
