Rear wiper blade never worked after purchasing from previous owner. Does not move or make any sound when activated. Just want to find a way for me to fix without going to mechanic.
Rear wiper stopped working, could hear a clicking. At the same time battery kept dying, so I disconnected wiper motor. Battery was fine after that.
Wiper motor is intermittent, I have replaced the motor and switch still the same. Works when cold (below 65) but not when warmer. Last item to try is the relay.
Rear wiper will go up, but not back down. Will reset after vehicle has been shut off and restarted. Have not have it repaired yet.
