It's the switch because the motor is getting power to go up but not down.
If you press the switch and hear the motor running, the the gear kit needs to be replaced. If you do not hear it, look at the dome light and see if it dims when you press the switch. If it does then you have a bad motor.
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
Hi, The problem with your pass side window is the drivers side power window switch. I have had this same problem on my 1993 Aerostar.
The front passenger window will not go down on a 93 Jeep Grand Cherokee if the motor or switch has failed. This is common when water gets inside the motor.
If it is just the passanger side don't bother with the fuses. the wiring does go thru the drivers side and then to the passanger side. Use a voltmeter at the passenger power window motor. If you get 12V to the motor it is probably bad. If you don't have 12V at the motor the wiring to it is probably bad. Make sure you didn't accidently turn off the passenger window switch at the drivers side door.
the switch is on the door panel approx four inches from the window, this is the only switch that sends power to the window regulator motor (window motor).
common probem with the 190e class vehicles. he problem is he motor and regulator assembly. find a used one in the wrecking yard and replace the complete assembly with cable regulator and motor. good luck
Check to see if you are getting power to the motor - if so probably a bad motor If not check switch check for an open wire to the switch
You are going to have 2 things to repair with this problem. The window switch and the window motor. The weak motor has melted the inside of the switch. Yep...been there,done that.Replacing the motor wont fix the switch and if you replace the switch the weak motor will melt the new switch.
A power window relay switch relays the power from the car's battery, to the switch itself, and then to the window motor. When pressing the button inside of the car it allows the power to go from the relay switch to the motor and roll the window up or down.
9 outta 10 times it will be a bad power window motor. I rarely see the window switch go bad.
Did you check for power to the motor? If the switch doesn't work then the motor won't work. If there is power to the connector that hooks onto the motor then the part may be defective, if not then trace it back.
