Passenger Side Window Does Not Operate With Master Switch

  1. With ignition in RUN or ACC position, check operation of driver's window. If driver's window works, voltage exists in master switch. Place master switch in UP position and check for voltage at Dark Blue wire.
  2. If voltage does not exist, replace master switch. If voltage exist, check for open between master switch and passenger side switch.
