Overview

The wiper and washer system is controlled by the central junction box (CJB). All wiper functions for the front and rear wipers are controlled from a multi-function wash/wipe switch assembly located on the steering column.

For information on the description and operation of the system, refer to section 501-16 of the workshop manual.

. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step

. 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.
  Because the DTCs are stored in more than one module, a complete vehicle read is recommended

Symptom chart

Symptom Possible causes Action
Wiper blade(s) drag/judder across the windshield/rear window
  • Contamination of the windshield/rear window
  • Incorrectly installed wiper arm(s)
  • Wiper arm(s) incorrectly aligned to the screen
  • Wiper arm(s) spring tension inadequate
Clean the windshield/rear window. Check for the correct installation and tension of the wiper arm(s). Refer to the relevant section of the workshop manual. Rectify as necessary.
Very slow operation of the wiper(s) across the windshield/rear window
  • Low battery voltage
  • Front wiper linkage seized or fouling
  • Wiper circuit fault
  • Wiper switch fault High resistance
Check the battery condition and state of charge. Check the wiper linkage for fouling. Disconnect the motor from the linkage. Refer to the relevant section of the workshop manual. Check the linkage operation. Check for DTCs indicating a wiper circuit fault. Rectify as necessary.
Wiper(s) inoperative
Noisy operation of wiper(s)
  • Wiper motor/linkage fault
Lift the wiper arm(s) from the windshield/rear window and recheck the noise level during the wiper sweep operation.
Noisy operation of washers
  • Washer motor(s) faulty
  • Washer system blocked or partially blocked
Listen for washer motor operation. Check and top up washer fluid level. Check and rectify blocked washer circuit. Check the wiper/washer circuit for DTCs indicating a fault. Rectify as necessary.
Washers do not operate
  • Fluid level low
  • Washer circuit blocked
  • Washer circuit faulty

DTC index

:
  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).

:
  Intermittent faults may cause DTCs to be logged, however some DTCs may be cleared during an ignition off, ignition on cycle. Carry out a road test (if safe to do so), check the functionality of the system and retrieve any DTCs before turning the ignition off.

:
  For additional DTCs, refer to section 418-00 - Network Communications in the workshop manual.
