Fix a Windshield Wiper Arm that Doesn’t Move
We’ve had a lot of rain recently. That’s a good thing as it pulls Maryland out of a short lived drought. However, it’s not such a great thing for my gimpy passenger side windshield wiper. For a little while now, the passenger side wiper wouldn’t always move, and when it did, not very far. This kind of problem can often happen in colder areas where the wiper blade freezes to the window and then the driver (me) tries to use them. I got some good advice on fixing the windshield wiper arm and here’s what I did.
Broken Windshield Wiper Arm
In reality there were a few problems. Like I said, the wiper arm only moved intermittently. It seemed to work best on the middle speed but even that was spotty. Secondly, the wiper arm didn’t make a full motion. It had a short abbreviated stroke. Finally, the wiper arm would crash into the plastic guard on the down-stroke. The first two problems can occur because the nut securing the blade has come loose. The last problem happens when the blade position is misaligned.
How to Repair a Broken Windshield Arm
- Step 1: The wiper arm is connected with a nut behind a plastic cover. Remove the cover by hand. Be careful as the covers will break easily.
- Step 2: Remove the nut with a socket wrench.
- Step 3: To remove the wiper arm, put a little pressure on the base of the arm while pulling straight off the spindle. It may need a little jiggling to get started.
- Step 4: Inspect the connection between the spindle and wiper arm to see if it’s stripped. If so, you may need a professional to replace it.
- Step 5: From inside the car, turn on the wiper blades and let them complete a sweep. This step allows you to properly align the arm so it doesn’t crash into anything on the down-stroke.
- Step 6: I took some plumbers tape and wrapped it around the spindle. Ultimately, this is a temporary fix, but it should help make a tight connection between the arm and spindle.
- Step 7: Replace the wiper blade. Set it in the proper place on the windshield and press the arm onto the spindle.
- Step 8: Replace the nut. Tighten the nut, but not so tight the blade cannot move. Try it out before continuing.
- Step 9: Snap the plastic cover back into place.
