Pinpoint Test 3

PINPOINT TEST 3: SINGLE POWER WINDOW IS INOPERATIVE - PASSENGER POWER WINDOW

Normal Operation
Under normal operation, when the driver window control switch is commanding the passenger window DOWN, voltage is sent to the passenger window control switch through circuit (T/LB) and ground through circuit (W/Y). When UP is commanded, voltage and ground from the driver window control switch is reversed. Voltage is supplied to the passenger window control switch through circuit (LB/B). Ground is provided by the driver window control switch (at rest) through circuits (W/Y) and (T/LB). When the passenger window control switch commands the passenger window DOWN, voltage is sent to the passenger window control motor through circuit (Y/R) and ground through circuit (R/Y). When UP is commanded, voltage and ground from the passenger window control switch is reversed.

Possible Causes
- An open in circuit (LB/B), (W/Y), (T/LB), (Y/R) or (R/Y)
- Driver window control switch
- Passenger window control switch
- Passenger window motor
- Smart junction box (SJB)
