2016 Auto Windshield Wipers Going Spastic

Recommended Posts

I have a loaded 2016 MKX Black Label.

The car has the automatic windshield wipers. You don't have to touch them, they come on & off when needed.

 

The problem that is driving us crazy is that when the wipers are in pulse-wait-pulse mode the wipers will randomly jump to the fastest speed possible and stay there for several seconds. Then it returns to pulse mode.

 

The dealer has told us that the system is not throwing any fault codes so there is nothing they can do...... They claim to have called Ford Corporate and spoke to an engineer that said there was no known problems with the system.

 

Anyone else have this issue with their Ford? Was the Dealer able to fix it?

If so, what did they replace?

sounds like maybe the sensor

The basic areas of failure would be:

•Wiring, terminals or connectors

•Multifunction switch

•Wiper/washer module

 

I would suspect the switch 1st, corrosion 2nd and the wiper module 3rd.

 

Try wiggling the switch to see if you can initiate the problem.

 

Does this only happen when it's raining? Or when you use the washers? Or only on a dry windshield? Do you have rain sensing wipers?

The most common issue is something on the windshield in front of the sensor (behind the rear view mirror). You’re not supposed to use Rain-X or put any kind of treatment there. Try cleaning that area really well. I’ve found barkeeper’s friend works well (similar to comet cleanser) for getting off oil and residue that winded won’t touch. Just make sure it says safe for glass.

I too have rain sensing wipers and have had the wipers speed up on their own when the rainfall is very heavy. Once they have "satisfied" themselves that they can keep the window clear they slow down again.

A tip for cleaning windshields from detailing specialists, use 0000 steel wool.

 

Yeah, the thought runs contrary to human logic, but it works superbly. Just be sure to use 0000.

Or go nuclear and use 0000 steel wool AND barkeeper’s friend!

What say you all to; Glass Cooktop Cleaner & polish?

Just a thought, haven't tried it yet.

Some may be OK, others not. Depends on presence of abrasives & other chemicals. Brands differ significantly. I would check MSDS for contents. Also, some contents might be harmful to wiper blades. Plus, elevated expense of cooktop cleaners and necessity of having to hose off a creamy mess might deter some folks.

I use windex, then a degreaser ( Chemical Guys No Nonsense invisible super cleaner), then clay bar the glass,(I use Mothers California Gold clay kit), then polish it with Meguiar''s Gold Class Carnauba paste wax. Then buff with a microfiber towel.

Windshield stays clean and rain beads better than Rain-x for at least 6 months. And I go through the car wash every week.

You must try this by your own because these little things can be done by own but doing windshield replacement and repair is not possible at all.
