Wipes High Speed In All Positions

Wipers Run At High Speed With Switch In Low Speed & Wipers Operate In Intermittent Mode, But Each Wipe Is At High Speed

Note: Whenever a wiper motor malfunction occurs, ensure wiper motor wire harness is properly connected before starting with normal diagnosis and repair procedures.
1. Disconnect motor connector, using two jumper wires connect one between battery positive and terminal three of motor wiring harness connector. Connect second lead between battery negative and terminal four of motor wiring harness connector.
2. If motor runs at low speed, check for faulty HI-LO wiper relay, then check for crossed wires in harness from HI-LO relay motor.
3. If motor runs at high speed, check for crossed wires in motor pigtail wire connector.
4. Using a suitable ohmmeter, check for short to ground. Disconnect J3 24 way connector from body controller and remove intermittent wiper relay.
5. If none of the above conditions are present, replace body controller.
