remove switch from where it is mounted
using a wire , bridge the connections.if switch is bad, it will work the motor while bridged
Use a test light to see if the motor is getting power. If it is then motor is bad. If it is not getting power "jump" the wires on the switch to see if window will operate, is so switch is bad
It's the switch because the motor is getting power to go up but not down.
Unless you're into wasting money by just throwing parts at it, the first step to any repair is diagnosis. Clearly, something isn't working - exactly what, you haven't told us, but presumably it results in your power window not working. Assuming the other power window works (since we don't know that, either), then you're looking at three likely culprits - a bad window motor, a bad switch, or faulty wiring. Start by testing the switch to see if it's getting power and relaying power when it's depressed. If it's not, then replace the switch. If it is, then move on to the electrical contacts at the motor, and see if they're getting power. If they are, then you need to test your window motor, and that's probably your culprit. If you're not getting power at the motor, then you need to trace the wiring between the motor and the switch, and find any breaks or shorts in the wiring. If your problem with the window is something else, then you need to tell us what. Kinda difficult to tell you how to fix something without knowing what the problem is.
To determine if the power seat motor is bad or if the switch is malfunctioning, first check for any signs of power at the switch. You can do this by using a multimeter to test for voltage when the switch is activated. If the switch is receiving power but the seat doesn't move, the motor is likely the issue. Conversely, if there's no power at the switch, the switch itself may be faulty.
how do you change a window motor on a 93 aerostar or can you please tell me how to get the windows down without the motor... my e-mail is snakespittbulls@yahoo.com
You need to open the door panel, unplug the motor from the connector, apply power and a ground wire to the contacts on the motor side of the connector. You make the motor go up or down by just switching the 2 wires back and forth between the 2 contacts inside the connector, If the motor runs, the switch is bad.
Buy a chilton's or haynes maintenance manual. They tell you everything. I had to replace my drivers side window motor. Not too hard.
passenger window does not work getting power when i press the switch getting power on both sides of wire tested motor works
If the window won't go up from only one switch it is most likely that switch. If it won't go up from the driver controls or the control on that window's door, then you probably have a problem with the window motor.
Tell me if just one window or all of them quit working
Had same problem with mine. Turned out to be the motor, but could also be the switch or wires.
The yellow with green wire goes from the switch to the relay which is to the right of the speaker and then from the replay it changes to yellow and goes to the motor.
