I'm having an issue with the passenger front power window. Using either switch (driver side, passenger side) it only goes down, not up.

I pulled the regulator assembly out of the door and it will go up and down when applying 12v directly from a battery.

I also put my meter on the connector that plugs into the regulator and checked I'm getting 12v and -12v from both switches on the car.

Not sure what else to check.

 

FYI - This turned out to be the driver side window switch.
