My drivers side window switch sometimes won't do anything, then it suddenly works and the window goes all the way down. It doesn't happen everytime, just randomly. Does anyone know what the problem is, and what needs to be fixed?

Thanks!

 

Get a service manual, volt meter and check for power in the plug. If you have constant power, then its the switch itself that is cutting in/out.

 

Ok sounds good, I will have to do that as soon as I can. Thanks for the help!
