Method Four of Five:
Replacing a Faulty SwitchEdit

1. 
   1
   Locate the window switch panel. This is the button used to operate your window. It is almost always on the door, however, they are rarely found on the center console.
2. 
   2
   Remove the window switch panel. Be careful not to scratch up the door panel while removing the window switch, as it often requires prying. Using a shop rag or piece of cardboard under your prying tool can help.
3. 3
   Unplug the wiring connectors from the switch. You will need to test these connectors to make sure that they are providing the appropriate 12 volts to your switch.
4. 
   4
   Use your multi-meter to probe each connector. Set the multi-meter for D/C volts and put the prongs of your multi-meter into the connector. It should read 12 volts.
5. 
   5
   Check the wiring on any switch that has a low voltage reading. Tighten any loose connections, and clear away any corrosion.
6. 
   6
   Test another switch. Take a switch from another door and plug it into the connectors on the malfunctioning door. If you are able to operate your window using this switch, then the original is bad and will need to be replaced.
7. 7
   Buy a new switch. Contact your dealership or favorite parts store and get a new window switch.
8. 8
   Install the new window switch. This can be done by plugging the connectors into the switch and popping the switch back into the door panel.
