I have a 1990 Ford Bronco II XLT and the wipers stopped working. I have replaced the motor, arm (combo blinker/wiper w/intermittent), and relay. Nothing worked. Also, made sure the fuse is good. The blinkers work fine but when I turn the wipers on intermittent, I can hear the relay clicking but nothing. I also verified that the motor is getting power. Does anyone know of anything else I can check or have any idea what else I can do? Thank you in advance for your input!

I think on that model, there's a relay or module under the dash. This is what they look like. You can also get it at Rock Auto, one of our sponsors and get a discount, being a member here. Look in the sponsor section for their code. Activant Cover-to-Cover

Yes I know, as I stated in my original post I changed that as well with no luck.

Sorry about missing that. It looks like you must have a wiring problem. Do you have a Haynes or Chilton manual? The Chilton usually has better diagrams. That's going to take some time following all the wires. If I had access to a diagram, I'd see where the best place to look is. I'll see what I can dig up.

Refresh my memory, but does the Bronco2 have a multi-function switch? If so, that would be the first place I would look. On newer models, the multi-function switch is what integrates the turn signal and wiper controls into a single lever. It is generally an easy component to fix on fords (not so much on GM's). The problem with these switches is that some of the many contacts inside (often those for intermittent wipers) wear out. so that while the turn signals may work fine, the wiper portion of the switch is bad and it all needs to be replaced as a whole compnent. Don't worry, these are not that expensive.

It doesn't sound like you hadn't addressed this part yet. And I might also mention that you did not say that you had checked GROUND to the motor, though you did check power. It could be that the relay circuit completes the ground side of the wiper circuit. With a bad wiper switch (multi-function), that the relay is not activated and the ground is not completed.

I think my hypothesis fits all of the information given, though you will have to check it out for yourself. best of luck, keep us posted so we can all learn from your efforts.
