Windshield Wiper Issues and Fixes

Mercedes-Benz windshield wipers are used to clean your car’s windshield from rain, snow, and debris so that the driver has a clearer view of the road.

There are common windshield wiper issues which Mercedes-Benz drivers experience. Here are a list of possible issues and how to troubleshoot them:

1. Mercedes-Benz windshield wiper runs, but the arms remain static.
The windshield wiper arms could have seized at the time where they pivot around the mechanism. The teeth on the wiper motor gear also may have worn out causing the wipers to stop moving. It could be possible that the wiper arms or linkage is broken or the bolt is loose.

Lubricate the mechanism to help free the arms up. Turn off the wiper motor and try to move the wiper arms manually across the windshield. Inspect the link between the wipers and the wiper motor. Tighten the bolts that hold the windshield wiper arm in place. Make sure there is nothing that obstructs the wiper blades too.

2. Wipers stopped working after the arms were replaced. The windshield wiper will no longer work after you properly install the new wiper arms. If the wipers were working earlier, then it should work with the new arms.

Look at the hood. The hood on a Mercedes needs to be closed for the windshield wipers to operate.

3. Mercedes Benz Windshield Wipers work erratically. This common problem is normally caused by defective Light and Rain Sensor for Automatic Headlights and Windshield Wipers. The wipers may move too slow or fast if this sensor is defective.

Calibrate the wipers by hooking up a diagnostic scanner or replace the defective sensor.

4. Windshield wiper has stopped working completely. This is typically a problem in your Mercedes-Benz windshield wiper fuse.The procedure is very easy and can be done at home. Look for the windshield wiper motor fuse box. Use the fuse chart to pinpoint the corresponding fuse for the windshield wiper motor. Check out the fuse. Ensure the fuse is not burned out. If it has burned out, replace the fuse with a new one but with the same ampere rating. Sometimes, replacing the windshield wiper motor fuse may be all that you need to do to fix your Mercedes-Benz wiper problem.

If none of the steps fix the issue, call a Mercedes Benz service Laguna Niguel mechanic like those at Laguna Niguel Auto Center.
