Wiper Control Module

Wiper Control Module
On the 94 F150 there is a "wiper control module" located behind the glove box. In fact to get to it you have to remove the glove box. Does anyone know what this thing does? I'm having some funky problems with my wiper system and would just like to know what this thing does.

When I push the washer button, I can hear it clicking behind the glove box.The wipers come on but no fluid comes out. The problem is intermittent. The pump is good, hoses are open, and nozzles are clear. I tend to think the switch is OK because it must be making contact in order to make the control module click.

I know you said the module clicks but just for grins and it only takes a few minutes pop the cap off the end of the switch on the column then remove the screw and slide off the rotating part. Now clean the contacts with alcohol or contact cleaner then lube with petroleum jelly or some light grease then pop it back together and try it again. I've had to do this with every ford I've owned with this setup.

Mine did exactly the same thing... clicking near the glovebox, some of the intermittent settings wouldn't work, etc. Anyway, you need to change your MFS (turn signal switch). I did last weekend and it's perfect now. Advance has them for sixty bucks and all you need is to unscrew 3 phillips in the belly of the steering column molding and 2 T20 torx screws that hold the switch on. Unplug the two plugs and put the new one in. 30 minutes and I guarantee this will fix it. The guy at Advance will probably mention how many he sells, too.
