What caused windshield wipers to fail?

Do you know what a wiring diagram is ? A wiring diagram for your vehicles windshield wipers electrical circuit would show all components involved . You would need a wiring diagram for testing ,so you know which wires too test . It would show the fuse location - amperage etc.... Which of these is your vehicle - Notchback or hatchback or station wagon .

Windshield Wiper System
The windshield wiper system consists of a wiper motor, a linkage, a wiper arm and a blade, and a wiper/washer switch. The windshield wiper circuit incorporates a self parking device which consists of a worm gear and a cam plate in order to keep the circuit engaged temporarily when the switch is turned off. The wiper system is driven by a permanent magnet-type motor. The windshield wiper motor is mounted on the dash panel and is directly connected to the windshield wiper linkage.
The windshield wiper motor has 2 speeds, LO and HI, and also has intermittent wiper capability. The wiper switch is an integral part of the wiper/washer switch. Windshield wiper operation is actuated through the lever on the right side of the steering column.

Make sure wiper arms are tight they are on a spline also where the wiper arm transmissin conects to the wiper motor therw is a nut that holds a z shaped bracket that losens up and oblongs the rectangular slot so the wipers stop with the least resistance.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/craig_a14a43e01fd0835a

replace wiper motor the seal on motor is bad water entered and shorted at motor then dried.honda had a recall for same problem.

May have to check out if the vacuum motors have the vacuum tubes attached but this may take a lot of work to disassemble the heating ventilation air conditioning out of the dash and underneath the dashboard. If rain enters the compartment under the dashboard, the pan that is designed to catch water may be disturbed or cracked somehow. Try to check fuses for a/c and the heating, the cruise control, and windshield wipers to see if there is an obvious electrical issue there. The vacuum leak is not related to the windshield wiper motor not working.

Good luck on this repair.

check to see if the wiper arms are binding, something is causing a feed back to the motor to strain. Blowing a 25 amp fuse is serious, and could cause many more problems, check for a good ground, clean all grounding wires in the system for that fuse, if you wrapped the wires and it quit for a brief time, one of them could be broken or burnt to the point that when they heat up and expand they simply can't complete the circuit

If you lift your hood, check the wires that are for your windshield wiper fluid, I had the same problem and because the wires were being pressed against the molding water was able to drop down onto the engine. When ever it rains really hard felt like the truck was going to cut off. But when the sun was out my baby would pur like a kitten.

Car has rain sensing windshield.Most likely you have the wiper on/off level in the intermittent position,which turns on the sensor. When the sensor detects moisture or even dust sometimes. It turns on wipers. Just make sure the wipers are off and not in the intermittent position.

get it down to the gararge to get checked out !!!!

the wiper system has a series of linkages, they are located at the bottom of the windshield (under the plastic at the bottom of the windshield) there are pivots that connect the pieces together and one of them has likely worn out and disconnected itself from the system.....if you are handy it isn't a big job.......just remove the plastic cover at the bottom of the windshield(usually held in place by several screws and sometimes a few clips) and locate the failed part them replace it .Good Luck!
hope this helps! thanks for choosing FIX YA!
