try replacing the windshield wiper moter, and check for damaged wireing that could be causeing a short and blowing fuses.
your windshield wiper motor might burnt out or a fuse might burnt out
burnt fuses
either your motor burnt out or you have a faulty switch that turns them on. Or check the fuse
You probably have a short in your electrical system. Also the fuse may be burnt out on the horn.
you will need to replace the wiper motor. there is a SET OF CONTACTS IN THE ASSEMBLY THAT STAYS TOGETHER TIL IN THE STORE POSITION[BOTTOM OF WINDSHIELD]. THIS IS EITHER BROKEN OR BURNT OFF, THUS DISABLING BOTH ACTIONS
There are a few reasons why a windshield will stop working. The fuse could be blown, the motor could have died, the wiring could be burnt, or it may not be getting enough electricity.
There are lots of possibilities: Check the fuse and make sure it is good. You may have a burnt out the motor. You may have simply 'stripped' the wiper motor connection. There is a bolt on that connects the wiper to the motor. Tightening it may be enough to get it taken care of.
A ballast that smells burnt is going bad. The ballast will have to be replaced to fix the problem.
The resitor is probably burnt out on the high mode
in the kick panel on the drivers side forward of the door there is a control box velcroed to the inside. this is the intermittent wiper control box if your wipers dont park or they wont spray windshield fluid this box is more likely the cause. a quick way to test this is to disconnect the box on both ends. then connect the two plugs together. your wipers will work in the low and high position only but they will park when shut off, also the windshield waasher fluid should spray again too. what you need to do is replace that control box, or if you think you can fix it open it up and look for the burnt solder strip on the board. I fixed mine three times this winter alone and all i used was stranded wire copper wire pieces looped around the broken solder strips
Remove the head and have the valve reseated or replaced.
Park it in the sun. Ours had burnt from the sun and is now curling backward away from the windshield!
