Dodge Ram 1994-Present: Why are My Wipers Not Working?

The Dodge Ram's windshield wipers can stop working for a number of reasons. Here are all the possible causes.

This article applies to the Dodge Ram (1994-Present).

Typically speaking, windshield wipers are an afterthought; that is, until they stop working. When this happens, it’s generally noticed during inclimate weather situations, and their inability to function properly renders the car all but undrivable. If you find yourself in this situation, the good news is it’s fairly easy to diagnose. That’s because with this particular system, it’s either mechanical or electrical. Run through the following list of possible reasons to see if you can figure out why your windshield wipers are no longer working, and what you should do to remedy the situation.

Materials Needed

  • Socket wrench
  • Screw driver
  • Hammer
  • Fuse (as necessary)

Step 1 – Check for a blown fuse

A rare occurrence, but this does happen now and again. Check the fuse panel to see if the wiper fuse has blown. Replace the fuse if necessary. Check your owner's manual for the location of the wiper fuse.

Step 2 – Check for power going to the windshield wiper arm

To do this, you will need to remove the wiper arm. Simply pop the joint cover off, and remove the bolt using a socket wrench. Place a flathead screw driver underneath the base of the wiper arm and hit the top of the screw – the blade should pop right off.

Next, remove the screws of the soffit and lift soffit from the car. You will now be able to see the electric motor that runs the windshield wiper arms. Follow the motor line to its electrical connection and note its placement. Now go in to the car, place the keys into the ignition, turn the car on and turn the windshield wipers on. Go back out and check the electrical connection with a multimeter to ensure the motor is getting power.

Take time to run the multimeter along all of the wires—sometimes they may go loose or accidentally short. Re-connecting them or replacing them as needed could solve your wiper blade problem.

Step 3 – Check for worn out parts

If the motor is getting power but the arms are not moving, then in all likelihood, the problem lies in the motor. If this is the case, then you will need to replace the motor. This is best done by a professional. A windshield wiper blade and all of its supporting components are exposed to a lot of friction; as such, parts tend to wear. This can lead to the wiper shaft jamming, bushing crumbling away, and disintegrating mounting blocks. Check all the parts associated with the wiper system and replace worn out component as necessary.
