Both window switches (pass and driver) are bad. They work fine for making the windows go down but up is a no-go!!!! I can sometimes and I do mean SOMETIMES get them to go up by jiggling the switch and pressing on the switch at different angles so I know the motors arent bad. Is there anyhting I can do as far as servicing the switches. Do they corode over time? I really dont want to have to source used ones and pay around $35 a piece.
