Replace the switch. There are no "user parts" inside that can be repaired, and the labor to fix a switch will be far greater than just buying a new one.
Bad relay/window motor/switch/wiring...........
I'm currently having the same issue and from what I've gathered over the past week online, it's one of two things. Either the window switch/connection is faulty OR the regulator. Mine happens to be the switch because the driver side switch for the passenger window works fine. Now my problem is if the passenger and driver switch mechanisms are interchangeable when purchasing?
Probably a weak power window motor or the window regulator is starting to act up
try open the ignition press the window switch down of the side that doesnt work n slam the door at the same time
Window lock switch is out change the master switch.
You installed the switch wrong.
you probably need to clean and re-grease the window motor
It is important to keep everything in a car working well. When a power window stops working, it is important to make repair it by replacing the window motor, the blown fuse or the wiring that may be causing the windows to not function. If the window can go down but not up, the power window motor and fuse are working. Check the switch for dirty contacts and/or wiring for damage.
If equipped, the lock out switch is on the driver's door.
To get to the side mirror switch on a 2002 Dodge Intrepid look on the driver side door. The mirror switch is located just above the window up and down switches.
just a litle to the passenger side of the distributor
the motor and the switch both work but the window will not move
