Introduction: Troubleshooting a Nonfunctional Windshield Wiper.

About: As of April 2017 I have decided to no longer post on instructables. The fact that several of my published works have been removed without my consent is inexcusable. Also the insult of an author having no co...

The rear windshield wiper on my wife's car stopped working. Time for troubleshooting!

Step 1: Fuse.

The fuse box in the dashboard has a blown fuse for the wiper. This fuse blew for a reason and I will not replace until I have investigated the wiper.

Step 2: Removing the Wiper.

Using wd40 and a 12mm spanner with Ratchet, I took off the wiper.

Step 3: Removing the Motor Assembly.

The electrical connector needed to be disconnected. A 22mm nut had to come out where the wiper was. Also three 10mm bolts were removed that held the assembly in place.

Step 4: Checking the Motor.

I powered the motor via my bench power supply and it worked fine! Of course the generous lubing of wd40 helped alot here.

Using a torx screwdriver, I opened the gear assembly and all looked well. I used my finger to spread some of the oem grease back onto the gears. I then mounted everything back up.

Step 5: Completion.

Mounting back the assembly and wiper was straightforward. I put a new fuse in place and tested the wiper on the vehicle. It ran smoothly!

No more yapping from the wife! Hooray.
