My Jeep Wrangler periodically has the wiper go on when using the turn signals.
Any ideas?
Is the windshield wiper switch on the same lever as the turn signals? If it is you may just be bumping the windshield wiper switch as you operate the turn signal lever. I’ve owned a couple of vehicles that would do this. If the windshield wiper switch is on the dash then it may be a faulty switch or windshield wiper motor.
