I have a 02 Taurus with a power window issue, the window wont go down on the drivers side front. I have replaced the motor and tried a new switch but no luck. Put volt meter to it and found that I had 12 volts in the up position of the switch but only about 1.2 volts in the down position of the switch. Is this broken wire or a known issue? Any help would be appreciated.[/b]
Basically, the control switch just reverse polarity to the motor and complete the circuit. You need to hot wire the motor and see if it takes' the window up and down.
If by hot wiring it you have both up and down, then its a wiring issue or bad switch. My guess its the switch. If you only have 1.2 volts to ground (check with another ground
to verify) either your motor is drawing too much current because its jammed or defective, or the switches or wiring path has a high resistance connection. you probably going to
need the factory wiring diagram to help you with this. this diagram should be simmilar
Thanks for the wiring diagram this may help. Have some additional information on this. Tried another motor and found that I have voltage of 12v in the up position and sometimes in the down position until I connect the motor, with back probing the connector I found that the voltage goes flat to 0.00 in both up and down and then after I unplug the motor I only have 12v in the up position but go back to low voltage in the down position. Also checked for any obstructions with the regulator and it was very smooth operation. Even with the motor disconnected from the regulator I have no operation of the motor. I am starting to lean towards the GEM
module, any ideas?
You have a high resistance contact somewhere. You need to hook the motor up, and start to backprobe at the 12 volt source of each window switch.
probe with the motor switch on and off. once you found the power loss, you found the problem. I bet you have 12 volts at the top of the switch
and it stays a 12 even when the motor is running in fault condition. My guess is yo have a bad switch, or corroded connection to the switch.
Its a pain, but take off the connector to both door switches, check them for corrosion and re seat them.
