The left side rear door window can no longer be closed using the master switch on the drivers' door. It works fine using the switch on its' own door.
I suspect a dirty or corroded switch contact, especially since the problem began as intermittent and gradually became worse.
I'd like to know:
1) proper switch removal procedure (svc manual just says remove it!)
..... i've tried to lift & pry, no success, don't want to damage anything!
2) has anyone had this issue & successfully repaired the switch?
