Got an odd electrical problem on my '01 WRX; passenger side window only works one way (up). Motor and both switches are known to be fine. When the switch 'reverses' the power and earth to make the motor go down, it 'loses' the earth. I know that is what's happening, as If I run a seperate earth to the motor when the switch is in the down position, it works fine.... any ideas? could there be 2 earths into the switch one of which is 'broken'?, anyone have a wiring diagram for the switch? cheers

 

btt anyone?
