The wipers won't turn off when key is on. Can change to slow or fast for wiper speed but not off or intermittent. Tried pulling the fuse but the fuse also shuts off the lights. Also can I just disconnect the wiper motor wire harness clip by just pulling or releasing the clip with a screwdriver? Thanks...

I found problem to be that corrosion sets in between the CAMS plates
that circle in an opposing fashion and does not let the wiper arms park
correctly. Be very careful with this mechanism if you have the cowling
off
TURN the KEY and WIPERS OFF and watch your fingers so you don't get them
caught.
WARNING if you leave the power on and try to move the arms This cam
mechanism springs to life and will try to self park the wipers on their
own so Turn the Power and Wipers Off.
SOLUTION:
1. With the ENGINE COLD, Spray a lubricant that FREE'S CORRODED PARTS
like WD-40 between the gap of the 2 CAM Plates and on Top of the plates,
or use some other automotive parts lubricant that free's corroded
parts(let it soak for 5 minutes).
2. Gently Try to manually move the arms back and forth a little bit so
that the spray works into the parts.
3. This may not be necessary but I had to do this the first time.
There is a notch in the top cam that has a STUD that locks the 2 CAMs
together. You can push on this STUD to unlock the cams by manually
moving the wipers(use a screw driver to push on the STUD and have a
friend gently move the wipers manually. Spray the area LIBERALLY with
with the Lubricant Spray and see if you can move the CAMS back and forth
and work the lubricant in.
Then with the wiper cover out of the way and all tools clear Try to
cycle the wipers HIGH and LOW, ON and OFF a few times it may stick the
first couple times with the wipers in the up position but I am confident
that the lubricant will work its way in and free these CAMS the way
they are supposed to.
Your wipers should self park after cycling them after 5-10times. This
should solve most of the problems with these
wipers and should be relubricated as needed. Clean up any extra
lubricant Put the wiper cover back on.

If you need to. Go to the fuse box and pull the fuse or relay. Temporary fix only . Still need to take a look at the switch
