Liftgate Washer System

  1. Turn ignition on. Turn liftgate wiper/washer switch to WASH position. Measure voltage at switch connector terminal "P". If meter does not read battery voltage, check fuse No. 1 and replace if required. Measure voltage at switch connector terminal "B". If meter does not read battery voltage, replace switch. Measure voltage at switch connector terminal "A". If meter does not read battery voltage, replace switch.
  2. Unplug liftgate washer pump connector. With ignition switch in OFF position, measure resistance at pump connector (Black wire) to ground. If meter does not read zero ohms, repair open to ground. Turn ignition on. Turn wiper switch to WASH position. Measure voltage at pump connector (Brown/White wire). If meter reads battery voltage, replace pump. If meter does not read battery voltage, check wiring.
  3. Turn ignition on. Unplug liftgate wiper motor connector. Place wiper switch in WIPE position. Measure resistance at motor connector terminal "B" to ground. If meter does not read zero ohms, repair open to ground. Measure voltage at motor terminal "A". If meter does not read battery voltage, check wiring to fuse. Measure voltage at motor connector terminal "C". If meter reads battery voltage, replace motor. If meter does not read battery voltage, repair open to switch
