I think the interval windshield wiper (IWW)governor sets about midways across the truck under the dash.It should have a plug with 10 pins(9 wires #2 is empty)

Are you saying you replaced the multi-function switch?It's most likely it or the IWW governor giving you the problem.

Critter thanks for the help, yes I replaced the MFS at colomn with no change, I knew there was a module for the int wipes somewhere but had no idea where

Ah crap sorry I forgot about that sucker.

When I did my 5.0L conversion, for some reason I had no wipers when I was done.
I replaced the multi function switch (yes 88 is similar) and still same thing. No power to the motor. tripple checked wiring, etc. Following the wires I found they led to a black box under the dash. Yup wiper relay box. Opened it up and parts fell out. It was toast. Laster 275K miles though Guess what? discontinued part! Figures.
Went to the junk yard, I now have about 8 of these suckers just in case.

Thanks for the reminder!

They're good about hiding stuff like that out of the way.Get's alot of people in to the dealer I guess.

Still have any left???
I replaced my MFS thinking that maybe it might be that, easy fix- or so i thought, still no low or intermittant(but at least i have hazards now!).....before I try and find one of those, could it be the relay? i'm trying the easy parts first....and would the part# be ER13 for that relay?????

Thanks for any info!
