Brakes failed when consumer pushed on pedal, vehicle rear-ended another vehicle, resulting in a mishap.
Windshield wipers will stop at any given time. If consumer jiggles circuit board they will come back on. But, problem is intermittent. The wiper motor was replaced twice and electrical connections were replaced but the problem was not solved. Jiggling the circuit board is the only solution so far.
