Default Does 99 F-body have a dedicated fuse for wipers?

My wipers will not turn off and the wiper pulse control module is bad once again.

I'd like to pull the fuse for the wipers but I cannot find the fuse?

Does this have a dedicated fuse for the wipers? Where?

Thanks..

Are you sure you don't just have a bad wiper switch? The pulse function is part of the same unit.

The problem started when I drove through the car wash, so I assume the pulse module that is located under the wiper motor got wet.

Where is the wiper switch located?

I'm sure it's in the owners manual.

What is the actual problem you are having with the pulse? I imagine that if your wipers are on constantly, you can't tell if the pulse is working, right?

The wiper switch is in a very bad place... Here's a thread documenting how you have to open up the column in order to replace it. Once you've gotten to this point, I've listed the procedure in step 21C. How-To; Steering Column Repair The wiper switch is quite possibly one of the biggest PITA parts I've ever had to replace. Its easily a 4-6 hour job for a first-timer. The part itself is also really expensive.

The connector for the switch is easily accessible at the base of the column. You should be able to test the switch there to see if its remaining open all the time and also test the pulse signals. You'll just need a wiring diagram to trace the wires.

BTW - The pulse lever is attached to a sleeve that rotates around the turn signal lever. Rotating the turn signal lever turns the wiper switch in the column, and the rotating sleeve engages the pulse part of the assembly, which is just another switch wrapped around the one for the wiper - all packaged in the same assembly.

If the problem ocurred imediately after I went into the car wash, isn't it likely to involve the pulse board next to the wiper motor and not the wiper switch?

Your chances of this happening randomly are probably just as good.

What's the first thing you do after coming out of a car wash? We turn on the wipers - which may have been the time that put your switch over the edge.

I guess it could be a bad module, but that should be pretty easy to test for at the steering column connector.
