I have a 6-cyl 3.0L Auto 93’ Ford Ranger. Ever since i bought it
(used) about a year ago, its had this annoying wiper problem. Here’s
the deal: The wiper is controlled by a rotating knob on the end of the
blinker stick. In order to control the speed of the wipers, you have
to turn it counter-clockwise, going from slowest to the highest speed.
The problem is that the wipers only work when you put it on "high"
speed. So in order to use the wipers, you have to turn the knob
clockwise all the way to where you cant turn it anymore for it to
work. You can see why this would be a nuisance, as I personally look
like an idiot putting my wipers on high in light rain. I would really
appreciate the help, as I dont want to take it to a shop because of
what a small, useless problem it is.

Thanks, Adam
