Neither the master switch in the driver's door nor the switch in the left rear door produce any result. All other windows working fine. But since the "down" worked normally, it seems maybe it is in the switch or the connection to the motor, not the motor itself? I don't have all of the tools nor the expertise to take the door apart and replace the motor (well, maybe, but it would take me days)but it reading around it seems like maybe just a switch fix MIGHT do it. I read in another posting that spraying the switch with teflon lube and letting it dry may help, does that make sense? And..which switch? If there is a problem with one switch, shouldn't the other one still work? Apologies for the uninformed questions. Hoping to avoid a four-hour round trip to the mechanic (we live in the middle of nowhere) and big bill if there is a simple solution. Thanks!
