Windshield Wiper Blade Arms

Wiper motor or wiper blade or arm ? There is one wiper motor for both windshield wipers . You would need to take both wiper arms off an remove the plastic cowling under wiper arms . The motor is under there . Plastic push pins hold the cowling . Open the hood after removing the wiper arms . Plastic caps on the wiper arms come off , 1/2 or 13mm nut has to be removed . Then rock the arms back an fourth till they come off . There may be a video on youtube showing how . Check it out .

Windshield wiper motors are generally easy to replace. You need to remove the windshield wipers and take off the small grill panel above the hood and under the windshield. You should see the motor in there. It simply unbolts and unplug the electrical connector and replace it with a new one.

Hi.

It's pretty easy, you do not need to know the position, the wiper motor always return to it's origin, just activate the wiper motor by briefly using the washer fluid switch for instance, let it finish it's movement. Next, you want to place the wiper arm with the longest blade on the driver side. Now for the height, most car's wiper sit from 0.5 to 1 inch above the base of the windshield so that should be what you're aiming for, if the wiper arms pinion has splines, try to pick the one closest to the windshield but not too close of course and repeat the same steps for the passenger side. Now you should check the wiper arm operation for collision, incorrect height or travel distance and adjust the wiper arm position accordingly. By the way, if you're lucky your windshield may have mark on the base of the tinting of the windshield to indicate the height of the wiper blade

bent/broken wiper arms under the base of the windshield..remove the vent cover and service/replace broken parts.

sounds like the connecting rod between both wiper arms either broke or one of the keepers popped off under the connector for that arm..since the wiper system IS NOT designed to wisk snow off the window once accumulated, this can an does happen.. even seen motors get burned out doing this..cleaning the window first will save this issue and the equiptment. need to acess this arm<take off the vented peice below the windshield and everything should be visible there..repost findings

I have the same problem with a 2001 Legacy wagon. The problem is not as simple as the solutions above. Mine are adjusted to park as low as possible when off. Even so, the blade on the drivers side goes all the way off the windshield. The Subaru dealer wants to replace the whole wiper blade transmission for about $450. Looking online it seems to be interconnecting arms and pivot points that connect the motor to the wiper blade arms.

why do you think the motor still works if the wipers don't move? Can you hear the motor run or can you see a little movement when you turn the switch on?

What happens when you activate the washers?

go to a salvage yard that allows you to remove the parts yourself. Then you can see how the motor and linkage assembly comes out.

The value of Dimension X for each vehicle is given in the Dimension X chart in the Specifications portion of this section.

1. Test the system.

Yes you can adjust them yourself. First you need to check that the wiper arms are not bent. If not, remove the cap at the wiper arm base, under it u will find a nut, remove this nut. you should now be able to remove the wiper arm. (it is comon for caravan wiper arms to be corroded on. If the arm dosen't come off, you may need to heat up the wiper arm with a propane torch. be careful not to melt the plastic cowel under the arm. OR you can use a wiper puller or a battery puller. do not force it, you can break the arm, DO NOT PRY AGAINST THE COWEL OR WINDSHIELD.
Once both arms are off, turn your van on and turn the wipers on. watch the wiper posts, turn the wipers off and watch the wiper posts return and stop in the "parked" position. Turn the van off. Install the passanger wiper arm first, it is positioned closest to the bottom an inch or two above the black cowel. It should be parrallel to the cowel. next install the drivers side wiper arm. it is positioned about 4 inches above the passanger wiper. again running parrallel to the cowel and passanger wiper. tighten the lock nuts down (do not over tighten) wet down your windshield with glass cleaner or windshield washer fluid and test wipers. If they still hit you can lower the passanger one a little or raise the drivers one a little (careful you don't raise the drivers one too much or it will 'jump' off the windshield at the top of the wipe).
good luck, hope this helps.

Sounds like you just nee to remove them and reinstall them in the correct position. Take them off, run the wipers for one cycle until they park. Install the arms so the blade is about an inch above the bottom of the windshield.
