Wipers won't turn off. what is causing this? can i fix it?

Might need to replace the switch

It is doubtful but maybe.. Check all the fuses and see if you have a blown fuse. If so replace fuse and see if that fixes your problem.

You can not solve by guessing

You need wiring diagrams, so you know what is
in that system & what is most likely the problem

Then you test to confirm,never replace any parts
until tested & fail a test

Wish & Hope-Push & Poke Not a diagnostic strategy

you have a bad wiper switch

Hi,
The 'stalk' that controls all these functions is faulty. Your truck SHOULD still be under warranty...Take it in.

Check the relay relay maybe latched on. See if there is an identical relay in the box and swap them if problem goes away replace relay.

You must have a bad wiper switch. By any chaqnce, is the headlight switch and wiper switch on the same stalk? The bad alternator may have shorted out the switch or it may have caused some wires to get hot, melted the insulation, and the heasdlight feed wire is passing current to the wipers-this would be hard to find, but look at the connector for the wiper switch, and check the wires both before and after the connector as far as you can to look for a wiring problem. I hope the new wiper switch fixes it.
Good luck.

There are only to things which could cause this.The wiper motor cover or the switch itself.Which is part of the multi-function switch.The cover is cheaper.It is located under the air inlet grill.The cover is on the wiper motor itself.There is a circuit board on here that causes this problem.It is the part you need to replace.Hope this helps.Good luck.

When they won't park it's 99% need new wiper motor

Hey Rk_
The switch may have gone bad.. or the module that controls the wiper... if the fuse went bad, it would not work.. REMOVE the fuse if you want it to stop...
