I was out driving in the rain today and my wipers just stopped working. They were working fine and then they started to shudder. Now they just won't work.

I noticed that when i press the wiper button in to squirt windshield wiper fluid on the windshield, nothing comes out. When I turn the dial for the different speeds, nothing happens. I do hear a clicking sound every time I turn and press the windshield wiper dial. I also notice they every time I press and turn the dial the battery voltage meter goes down. I looked at the fuse diagram and there wasn't anything for the wipers. Help!

Thanks in advance.

Oh yeah some truck info, it's a 1987 ford f150 xlt lariat with a 5.0 engine.

 

There is a wiper module over the top of the fuse box its a little black plastic box it hooks into the harness from the back of the wiper switch.

 

Ok so I went into the fuse box and saw and looked on top of it like you said and saw a little black box behind the plastic dashboard. It was held on by by what looked to be a plastic screw. It has wires coming out at both ends.. Hopefully it's the right one. I'll post pics up just to make sure. Anyway, if I did get the right module, how do I open it? I tried depressing the clips and the damn thing won't pop open. Are there fuses in it?

In the first picture, I'm pointing to where I found the plastic screw that held the plastic box in lace. In the second picture I'm pointing to the box after I got it loose.

 

I cant see to well in those pics that little black plastic box is right over the top of the fuse box. If you take the ***** off the head light switch and wiper switch and then pull the trim pannel off. Then take out the wiper switch follow the wires from the wiper switch down to the little black plastic box thats your wiper module.

 

Yeah I gave that a try too and was able to pop the trim off, but couldn't get the ***** off. I tried twisting and pulling and still nothing. I also didn't see any screws holding the ***** on.

 

Wiper **** pulls off, headlight switch has a button you push to release the shaft. When you open the box resolder the cracked joints.

 

On 87, wiper control is above the headlight switch.

 

Where is what it looks like.

 

If it was plugged into the wiper switch that's it. I don't remember exactly what it looks like but that looks like it. Open it up.

 

Oh yeah I saw that box. Mine wasn't located near the fuse box, it was actually in the engine bay on the driver's side toward the fire wall attached to the fender. Maybe my dad had it rewired and placed there or maybe that's just where it was stock. Thanks for the help! Turns out the wiper motor was bad and I just ended up taking to the closest Ford dealership earlier this morning to have it repaired. And they're done, so I can get my baby back when I pick it up tonight! I'm glad they still have parts in stock or ready at hand for these trucks.

Thanks everyone for all the help and for posting pictures.
