- Blown Fuse: Check the fuse that powers the windshield wiper fuse box or the fuse box located under the hood of your Caravan. If the fuse is blown, replace it with a new fuse of the same amperage.
- Faulty Wiper Switch: The wiper switch itself could be faulty, preventing it from sending power to the wiper motor. Try operating the wiper switch in different positions to see if the wipers respond in any way.
- Loose or Corroded Wiring: Check the wiring harness that connects the wiper switch to the wiper motor. Ensure the connectors are secure and free of corrosion or damage. Clean or repair any damaged wires as necessary.
Mechanical Issues:
- Faulty Wiper Motor: The wiper motor itself may have failed. Try tapping on the wiper motor with a rubber mallet or screwdriver handle while operating the wiper switch. If the wipers start working after tapping, the motor may need to be replaced.
- Damaged Linkage: The linkage that connects the wiper motor to the wiper arms could be damaged or disconnected. Inspect the linkage for any broken or disconnected components. If any damage is found, replace or reconnect the damaged parts.
- Seized Wiper Transmission: The wiper transmission, located at the base of the wiper motor, could be seized or damaged. Try manually moving the wiper arms by hand to see if they are stuck or difficult to move. If they are stuck, the wiper transmission may need to be replaced.
NOTE: If you've checked and ruled out all the above potential causes, it's advisable to consult with a qualified mechanic or auto electrician to diagnose and fix the problem accurately and safely.
