Hi guys,
Rear wiper not working. Have dismantled motor and all looks good. Free moving and motor runs fine with 12v applied directly.
I believe the issue is the signal/power going to the motor or else the electronic module in the motor.
What voltage/signal should come through the three wires that plug into the motor. I have measured 0v for Brown, 12v for Green and 12.4v for Grey/Black. Switching on the wiper switch causes an intermittent drop in the Green voltage every 5 seconds or so. Other voltages unchanged. Does this sound right?
If it is, I suspect the module on the motor and if not, perhaps the relay? Fuse is ok!
Thanks for any advice!
