Things You'll Need:
- Wiper blades
- Brake oil (WD-40 works as well)
-
Step 1
Raise the elbow on your windshield wiper into its locked position. To access the henge pin, simply raise the wiper arm. When it clicks, it will stand on its own.
-
Step 2
Inspect the henge pin and spring mechanism. Make sure that corrosion hasn't occurred to the point where they need to be replaced. While rare, this can occur in older cars. If there is minor corrosion, wipe it away with a rag.
-
Step 3
Lube the henge pin with your brake oil or WD-40. You will find the henge pin at the base of the wiper blade arm. Spray until it is well covered.
-
Step 4
Work the wiper blade arm back and forth several times, so that the lube gets into the crevices.
-
Step 5
Snap the wiper blade back down and test it. Turn on the car and shoot some windshield washer fluid on the window. It should be much more efficient when you clean it off.
-
Step 6
Repeat with the other windshield wiper arm. Perform this maintenance yearly.
