the switch may have failed as well. open the harness and look for broken wires or shorted wires and repair as necessary.

my first gess would be the switch baced on what you are telling me. see you add power and ground to the 2 wires @ the motor if it will run. you can switch power and ground on the 2 wires to run the motor the other way. this will let us know if the motor is good. if you have a test light see if there is voltage on the dkblue wire when the switch is in the up posostion. and voltage on the brn wire when switch is held for down. the switch will flip flop power and ground to run the motor up and down. will it work from the drivers master switch? does the driver window work ok? also see if there is voltage on the brn wire with the key on or engine running

It wOnt work on the master switch and I took my driver door apart and hooked up the motor to the drivers side and the motor worked fine so I don't think its the switch is bad, It has to be a wire issue, I looked at the with I could see, and it looked okay, the housing was a little melted but the actual connectors were fine
