The drivtoners window will go down but not up. I replaced the motor and switch thinking that was the problem. I also checked the old motor when this did fix the problem. The window motor turns in the same diretion wheter hitting the up or down.

Single wire BUS communication, so the module that controls the motor is suspect.
