Rear Windshield Wiper doesn't touch window

My rear wiper motor works fine, but when the wiper runs, the wiper doesn't even touch the window. the metal spring in the wiper is intact, but the "hinge" that allows the wiper to be pulled away from the glass is very tight, which doesn't allow the wiper hinge against the glass while it runs.

I suppose WD-40 is where I can start, but I thought I'd ask to see if anyone had similar problems and/or a solution.

thanks.

the metal hinge gets all junked up / rusts.

put some good silicone/water repellent lubricant and work it into the hinge back and forth - it'll snap right back to the window when done.

I gave it a shot with silicone lube and it seems better. I will find out for sure the next time it snows or rains.

thanks very much!

Take it to a car wash with a pressure wash wand and blast out the hinge and spring. (Wait till the temp is above freezing.) Then let it dry. Then lube it lightly. Mine wouldn't touch the window either and it was just gunked up with grime and salt.

Thanks for the tip, a little WD40 worked great.

You guys really provide a wealth of information here. Thanks!

I was having trouble with my rear wiper blades not making contact with the glass.
I came here and did a quick search, went and got a can of WD40 and sprayed the hinge and springs, and then worked the arm back and forth. Problem solved.

If I went to the dealer, I'm sure they would have told me the motor or the arm is messed up and it needs a full replacement.

OEM Rear Wiper Fixed

I spread the rear wiper arm flange with heavy duty needle nose pliers. I firmly held the arm with one hand while using the other hand to bend the flange with pliers. The metal was very stiff and a little knob thingy prevented grabbing right at the hinge, but I could bend both sides enough that the spring tension now keeps the blade firmly against the window when wiping. I didn't have to bend much, just enough to stop the binding at the hinge. It left a few scratch marks but not very noticeable, which I suppose a little electrician tape on the plier jaws or/and arm flange might have prevented the marks. The wiper now works like it should. Some quality bike chain lube on the hinge for good measure will help keep it working smooth.

Besides the lubing of the spring, which is the most important part of the wiper arm recondition, there's also another less talked about but also possible cause of the wiper malfunction.

Sometimes the wiper arm has been taken off and reinstalled incorrectly, making the wiper blade contact surface with the glass less than ideal.

Take off the wiper arm by popping off the cover, use a 1/4" ratchet with a 13mm socket to remove the 13mm nut. Pull the arm at the base straight up with some force to remove the arm.

Clean up and lub the spring as needed.

Here's the important part:

Install the arm by inserting into the screw with the tip of the arm aiming at the ground. This allows a very good fit of the entire arm to the base of the motor and eventually flush with the surface of the glass.

While holding the arm down with some force, gently bring the tip of the arm to the edge of the rear glass, making the arm and the wiper blade as horizontal as you can to the edge of the glass.

Now tighten the 13mm nut holding the arm to the base and put back the cover.

Doing both the spring lube and the arm re-position brought my wiper back to 100% functionality!

white vinegar for rust removal, I soaked the hinge up, wrapped it in plastic overnight then hit it with penetrating oil and its back on the glass.
