I have an 04 FX4 and the other day my wife tried to put the passenger side window down, it started to go and then slowly stopped. I can operate it just fine from the drivers side, but the switch on the passengers side is in-op? Anyone else have this problem? I have heard about faulty motors problems but not switches..

 

a switch will either work or wont... it wont slow down...

bad motors... i dunno.. some one else can chime in

 

You can easily have bad switches AND/OR bad motors, but, slowing down? That doesn't sound like a switch at all does it? And, if everything works fine from the other side, can't be a motor problem either.

I just recently took my "Door Lock/Unlock" switch off the passenger side to see if I could repair the fact that it no longer lights up at night. Short story here is no - those are the tiniest LEDs I've ever seen and there's no way, that I can see, to bypass them with others, or to repair their circuits). But, the contacts for the switch itself are easy enough to clean/burnish once you get the switch apart (which is a whole lot of fun too). Possibly some bulb grease on the contacts would prevent corrosion in the future?

Well the switch only slowed for a brief moment when she pushed it and immediately died..Basically it started going down and then died..I took it off, jiggled the wires, re-plugged it in and still nothing!! But I agree, can't be the motor because the other switch works perfect! SOmebody help me out here

 

okay.. if it works on one switch... it is either the wires or the switch that is not working...

get a test light and one side of the switch MUST have power to work....

if not, check the wiring

 

switch is probably bad

 

It is a problem with the switch on the passenger side, considering the driver's side switch still operates the window as normal.

The wiring is power from the driver's side switch contacts ( for the right window ) to the passenger's side switch, to the motor. The power is in series to the passenger side.

This is a pure luck item, where the passenger side switch has failed to the normal position ( contacts are connected through ), usually when the passenger side switch fails, the window does not work from either side, causing the where waldo diagnoses ( both switches and the motor seem to be in question ).

Here is the diagram for a SCab / SCrew power window, so you can see what I am talking about with the series wiring.

My driver's side switch failed ~20 months in on my 2006, I am guessing from it getting wet. The window would be slow to move, and some times I had to really mash the switch to get it to go up, and the contacts were the issue, so the down was fine, the up would be slow, due to a poor electrical connection ( high resistance load, using part of the power to move the window ).
