I just bought a used 1990 Ford F150 pickup truck. It's a 4WD with
manual trans and 302 engine. The problem is that I flipped on the
wipers to test them, and now they never shut off. When I turn the
knob all the way to the left the wipers only work once every minute or
so, but they never entirely shut off. This is getting annoying. I
thought I could temporarily remove a fuse but there is no fuse
labelled wipers. Unless there is something I am missing, I will have
to assume the switch is bad. I does not turn any further to the left,
pushing it turns the windshield washer on, and pulling the knob
removed the knob itself. Is there something I am missing?
If the switch is bad, I dont intend to replace it. The wipers work
and variable speed works fine. Besides I see no way to even get under
the dash without ripping out the whole fuse block and whatever else.
Too much work...... Probably too costly for the part too.....
My idea is to find the feed wire, (on autozone repair for this model
it shows a black wire with lt.green strips going to the ignition.)
Anyone know where I might find this wire without ripping the whole
truck apart? I'll just install a separate switch to kill the power
tot the wipers entirely when I dont want them on.
