I have a 2000 legacy sedan. The drivers window goes down but won't come up. Sometimes if you play with the switch you can get it up. So thinking it was the switch I got a used master switch from a on line parts supplier, put it in and same problem. Ran 12 v power to the motor and it works great in both directions. Did I get a bad replacement switch or is there a relay that's bad. What am I missing. Help.
