Help needed --my driver's side window not operating Motor is good, switch is good. What I need is a wiring diagram because checking for incoming power to master control, I have power to three of the four terminals but the fourth --no power. Catch is in the Haynes manual I have it indicates that the power supply is a white/ yellow wire but the lead that has no power is Blue/grey. Could the Hatynes be mistaken???
Thanks in advance as you folks always provide excellent info.
