power window and power lock problem

[luciani27]

hello. i'm new to this forum, due to a rather minor but annoying problem with my car.

as i was coming from work yesterday, i rolled down my driver side window, for a moment. when i pushed the button to roll it back up, it only came up halfway, then it stopped, and whatever i did, i couldn't get it back up. the problem is that not only my driver side window doesen'twork, but none of the windows in the car work, wether i use the button from the driver's door pannel, or the switch from each of the other doors respectively. another thing is that at the same time the lock/unlock doors switch stopped working as well. i checked the fuse but it seems to be ok.

another detail, that may or may not be significant, is that usually the switches for the windows and lock/unlock doors have a light, so you can see them in the dark. now they are still lit but very weakly, you can barely see that they are.

i hope someone can help me with a piece of advice, as it's been snowing for the last few days, and it's really, really cold.

thank you

When you say you checked the fuse, do you mean the one under the hood? My 99 Taurus has a 30 amp fuse in the box under the hood that is for the power windows, locks and seat. It's in the #4 position, which is the second from the left in the top row (closest to the engine).

yes, i checked that one too, but now i bought another one just in case my tester doesn'nt work properly. i also checked the wires that come to the switches, and i onlyget a voltage of 4 to 6, but not constantly, it just variates between 0 and these values.

Welcome to the forum!

What year is your Taurus? From your profile, it appears you have a 1997 Taurus, but it would be helpful to post that info when starting a thread.

When you measured 4 to 6 Vdc at the switches, was that using a ground at the switch, or a common ground from the body of the car? If at the switch, you may have a bad ground for the door or the switch. A bad ground could easily effect the intensity of the LED switch lighting as well. If using a body ground or similar, then you may have severe corrosion on one of the feed wires to the switches, likely where the wires go through the door jamb. There is a cylindrical connector between the body of the car and the door. I've seen wires get damaged or corroded fairly often in this connector. Not fund to repair, but I imagine it's not fun to drive with a window part-way down either.

If you measure the voltage to the accessory delay relay in the instrument panel fuse/relay box, do you have battery voltage there or only the same 4-6 Vdc?
