So my passenger side front window won't roll down with either the master switch or the door switch. Things I've checked so far: the fuses, relay and breaker are all good. The switch checks out with continuity. I'm getting 12.4 volts at the motor harness when I activate the switch on both the up and down control wires. I went to Autozone and bought a new motor and tried it in the parking lot and it didn't work. (I checked to make sure I could return it before I bought it.) Any other Ideas? Maybe a coincidence but the first time I noticed it not working was right after my battery died and I jump started it.
