Evening folks,
After my electrical issues at the weekend I've been checking the rear wiper circuits. Looking at the wiring diagram and some posts online the way I understand the system operates is:
- Rear wiper is earthed by the brown cable to the motor
- Constant positive supply to the motor via the green cable (when ignition is on)
- The console switch supplies power (when switched on) to the rear wiper via the green/black cable connected at the motor
The wiper will sweep due to the power from the green cable, however it will stop at the park position if the console switch is not on (guess there must be a break in the contact / track). If the console switch is in the off position the green/black wire is grounded which stops the motor at park.
Checking my switch (951 613 113 00) when in the on position, it correctly routes power to the green/black cable at the motor. However when it is in the off position there is no continuity to earth.
My question is should there be ? The diagram on the side of the switch would indicate there should be.
Thought I'd check though before opening the switch up and trying to fix it (or buy another one).
Thanks,
Andy
