Windshield wipers don't work but the motor runs . 93 Dodge Dakota

You must remove both wiper arms,open hood and remove metal vent panel that runs the width of the vehicle.You will see where the arm has falling off ,replace all bushings(4).NAPA carries them.

If the pump works, something should be flowing thru the hose to the spray nozzles.
And if the pump works, everything electrical is working.
How do you know the pump works ?

Tur the wipers on and tap the wiper motor. If it start to work replace it.

REMOVAL & INSTALLATION
(see Figures 1 and 2)

To remove the arm from the pivot, lift the arm to permit the latch to be pulled out to the holding position and remove the arm from the pivot with a rocking motion.

Fig. 1: Mount the wiper blade/arm as shown-Dakota models

Fig. 2: Mount the wiper blade/arm as shown-1994-96 Pick-ups

When installing the arms, the at-rest position of the blades should be determined before pushing the arm onto the pivot. For Dakota trucks, the tip of the driver's side blade should be 0.51-2.63 in. (13-67mm) above the cowl panel and the passenger's side blade should be 0.94-3.06 in. (24-78mm) above the cowl panel. For 1989-93 Pick-ups and Ramchargers, the driver's side blade should be 1.84 in. (47mm) above the windshield weatherstripping at the heel of the blade; the passenger's side blade should be 2.24 in. (57mm) above the weatherstripping. For 1994-96 Pick-ups, the wiper motor must be in the PARK position and the wiper blade should be about 0.85 in. (22mm) from the upper edge of the black-out areas at the base of the windshield.


Hope this helps to solve it.

There are bushings that go bad. They are available from a parts store. Ask or look under the HELP! section. the cowl panel will need to come off. replace ALL of the bushings.

If the motor is running, it's probably the wiper bushings are worn out. Get a set(Motormite)at your local parts store and replace.

Remove the wiper arms amd the panel between the hood and the windshield. There are teflon bushings on the actuater arms that wear out, they are cheap and available from the dealer but can be tricky to install because of the limited access.

THE PROBLEM HERE IS WHAT IS CALLED THE WINDSHIELD WIPER MOTOR PARK CIRCUIT, YOU MUST REPLACE THE WIPER MOTOR TO FIX IT. I DON'T KNOW WHY IT GOT BURNED OUT, WHERE THE WIPERS ON WHEN THE BATTERY WAS DRAINED?

There is a little hook like metal piece under your windshield wiper arm.When you push it to the right while pulling the wiper arm up it comes off
