Glass, Frames and Mechanisms (G1373074)

DIAGNOSIS AND TESTING
Overview

The glass, frames and mechanisms are of fairly straightforward design requiring no specialized techniques for diagnosis.

Some of the components from the description and operation section, such as the rain sensor and antennae are covered in other sections of the manual, so this section will provide basic diagnosis for the window and heated screen functions.

For information on the description and operation of the systems covered, refer to the relevant description and operations section of the workshop manual.

Inspection and Verification
  1. Verify the customer concern.
  1. Visually inspect for obvious mechanical or electrical faults.

Visual inspection

MechanicalElectrical
  • Window control switches condition and installation
  • Window motors/regulators
  • Window channels/runners
  • Window cables
  • Door window glass retaining brackets
  • Fuses
    • Central junction box (CJB) - fuse 7
    • Central junction box (CJB) - fuse 13
    • Central junction box (CJB) - fuse 17
    • Central junction box (CJB) - fuse 30
    • Central junction box (CJB) - fuse 31

  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto the symptom chart or DTC index.
      • Make sure that all DTCs are cleared following rectification.
Symptom chart
SymptomPossible causesAction
Window(s) inoperative
  • Fuse(s)
  • Switch fault
    • Front switch isolator fault
  • Motor/Regulator fault
  • Channel/Runner fault
  • Cable fault
  • Harness fault
  • Window circuit short circuit to ground, short circuit to power, open circuit, high resistance
  • Check the fuses (see visual inspection). Check the suspect window operation from the individual door switch and from the driver door master switch (it is unlikely that both switches would fail at the same time, so if the window is inoperative from either switch, suspect a fault other than a switch). If the inoperative window is a rear unit, check the function of the isolator at the master switch
  • If the concern persists and a noise cannot be heard when operating the door window glass, GO to Pinpoint Test B.
  • Refer to the electrical circuit diagrams and test the window circuit for short circuit to ground, short circuit to power, open circuit, high resistance
Window(s) 'one-shot' function inoperative
  • Window motor initialization required
  • Switch fault
NOTE:

Do not install a new window regulator assembly or motor for this concern.

  • If the battery has been disconnected, carry out the initialization procedure. Refer to the relevant section of the workshop manual. Check the switch function after initialization
Rear window does not defrost
  • Fuse
  • Switch fault
  • Relay fault
  • Element fault
  • Circuit fault
  • Check fuse 13P of the CJB. Check the operation of the heated rear window switch and relay. Check the element for continuity. Check the heated rear window circuit. Refer to the electrical guides
Window(s) noisy during operation
  • Channel/Runner fault
  • Cable fault
  • Motor/Regulator fault
  • Door window glass retaining brackets
NOTES:

  • Do not install a new window regulator assembly for this concern.

  • Door window glass retaining bracket adjustment procedure

  • GO to Pinpoint Test A.
Slow or partial window operation
  • Fuse
  • Switch fault
  • Relay fault
  • Element fault
  • Circuit fault
  • GO to Pinpoint Test C.
Rear door window glass bounce back
  • Window motor initialization required (using the manufacturers approve diagnostic system)
NOTE:

Do not install a new window regulator assembly or motor for this concern.

  • Using the manufacturer approved diagnostic system, perform window initialization
Front door window glass bounce back
  • Window motor initialization required
  • Channel/runner fault
NOTE:

Do not install a new window regulator assembly for this concern.

  • GO to Pinpoint Test D.
DTC index
NOTES:

  • Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system).

  • For a full list of seat heating function DTCs, refer to section 412-02 - Control Components in the workshop manual.
