The wipers on my 1998 Chevrolet Metro LSi started acting weird (i.e. slowing down, stopping mid-wipe). I removed both the wiper motor and wiper transmission. I attempted to test the wiper motor with a 12V battery. I connected the battery negative to the motor case for ground. When I connect the battery positive to the high pin (2), the motor spins at high speed. When I connect battery positive to the low pin (3), the motor spins at low speed. How do I test “park”.
pins on motor
| 3 2 – |
| 6 5 – |
pins on connector (from service manual)
| 1 2 3 |
| 4 5 6 |
where 1 and 4 are not used
where 2 is wiper switch output (high)
where 3 is wiper switch output (low)
where 5 is wiper motor park signal
where 6 is battery positive voltage
