Windshield wiperblade overshoots windshield

Check wiper transmission arms ..usually located under the cowl below the windshield.. fittings could be worn or loose..

Get a stick pin or sewing needle and stick in nozzle hole and adjust.

the wiper control arms bushings are worn out and need replaced..

Worn & or loose linkage

PULL WIPER FUSE......WAIT...RE-INSERT. IF THIS DOESN'T DO IT THEN YOU HAVE A SWITCH OR WIPER MOTOR PROBLEM. I AM ASSUMING YOU KNOW THIS VEHICLE AND FUNCTIONS WELL!

The wiper arm can be removed and re-positioned for proper travel.

If you grab the arm and pull it toward you gently (it should be spring loaded so you can move it) You can spin the wiperblade all around, sort of like a swivel. On the inside of the ARM, very close to the blade there will be a small black tab just sticking out about 1/4 of an inch. Push down on it and the blade will slide down the arm and disconnect. Once you get it, you will laugh. Very simple.

Hi:
Often this problem is caused by a filmy build up on the windshield. It could be from any kind of natural source, but often you need to go to great lengths to make your windshield squeaky clean.

Try wiping down the windshield with a soft cloth, soaked in a mild detergent...Nothing abrasive.

Then after that, use a high quality glass cleaner solution, such as windex, and go from there.

Hope this helps

sorry new mechanism its worn
