| Wipers and washers inoperative |
- Washers inoperative
- Wiper arm(s) incorrectly installed/aligned
- Steering column right multifunction switch internal failure
- Wipers and washers control switch circuit short circuit to ground, short circuit to power, open circuit, high resistance
|
- Listen for washer motor operation. Check and top up washer fluid level. Check and rectify blocked washer circuit. Check for DTCs indicating a wiper/washer circuit fault. Rectify as necessary
- Check the installation/alignment of the wiper arms. Ensure motor/mechanism is not jammed or seized
- Check if the wipers and washers control switch retaining screws are tightened according to specifications. Inappropriately tightened screws might cause steering wheel module failure
