The window comes down easily, but does not go up unless I move the button around and find a spot that makes contact. I do not know how to get access and expose the contacts so I can clean them.
How do I expose and clean power window contacts on driver's side. on 2003 Chevrolet Monte Carlo
Replace the switch! If you take it apart to expose the contacts, it's almost impossible to reassemble!! But if you have to try it the rocker switch (button) will come off but when it does be sure to find all of the pieces for reassembly! Switch on ebay! Super good price!! You can't even fool with it for less!
Have to take armrest off & the door panel .most likely its just a plug & that may be loose or u can buy some electronic spray cleaner for the plug & circuit board.
