I had never noticed this before, since I had never driven the truck in the rain, but the intermittent wiper timer seems to not be working. The continuous hi/lo setting work fine. When I turn to one of the timed settings, I hear a clicking from the glove box area and the wipers will go once and will not go again. Occasionally the wipers will get a couple repetitions at the slowest setting, and the fastest intermittent setting seems to work, but none of the others work. What could be the issue?

 

my bronco did the same thing, until they completely stopped working in the middle of a snow storm 5 miles from anywhere on a busy highway. (i called it hell trip, my trans blew up on this trip too) it was the multifunction switch i wanna say it was 100 bucks from the dealer in utah, and took about five minutes to install

 

ugh, I imagine that'll be fun to install. Is there any way I can test to be sure that's the faulty component?

 

continuity check through the functions would work i guess. i dont know where to find a diagram for that part though. and actually it only a few screws for the bottom of the column and two allen heads holding the whole thing it

 

There is a wiper delay box under the dash that works the intermittent wipers, I had one go it was about $75. a while ago.

 

could that have been the source of the clicking I heard?

 

interesting development... if I have the wipers on an intermittent setting and use the turn signal the wipers will go

 

that makes me think the contacts in the turn sig/wiper switch are bad

 

Chilton's wants me to believe I have to remove the steering wheel to get the switch off... so I have that to look forward to :|

of course, the airbag light is on, and none of the buttons on the steering wheel (horn and cruise control) work anyway, so maybe I'll have to take off the steering wheel anyway lol

 

what year is your truck?
