A challenge to the automotive design engineers who read this (who number, to the best of my knowledge, somewhere around exactly zero individuals):
Whereas windshield wipers (hereafter referred to as Wipers) are not mounted in the trunk nor are Wipers mounted under the dashboard by the heater nor are Wipers mounted on posts in otherwise deserted tropical islands;
Whereas Wipers are quite often found on the exterior of automobiles, trucks, trains, helicopters, and other such exterior applications;
Whereas exterior applications are, by their very nature of being exterior and not interior, exposed to the elements;
Whereas elements have a tendency, on a somewhat seasonal basis and driven by a chaotic system, to vary in such ways that include Wet or Cold;
Whereas certain regions have, at certain times of the year, the habit of experiencing both Wet and Cold at the same, or closely alternating, instance in time;
Whereas Wipers are designed to move by electrical and mechanical means;
Whereas those means may be halted in their tracks by even a small quantity of Wet that has become Cold;
Whereas at least one flavor of heat-application doesn't always reduce enough for the Wet to get out of the way;
Can you please design the frickin' Wipers so they don't burn their motors out or snap off their linkages or keep forcing their way in one immovable direction without resetting safely and calmly and waiting to try again later when the situation may or may not have changed; resulting in eventual success when the Spring Thaw happens or when whatever heating technology you allegedly have actually does what it allegedly should.
While you may consider it entertaining to design things in such a manner as they currently exist - akin to including a failsafe in all jumbo jets that forces the engines to prepare for takeoff any time they're started, even if that means flying at force into the nearest terminal - I'd really rather not have to replace any more wiper motors or wiper linkage or anything else involved in a fairly important piece of safety equipment.
A common problem - that of the blades freezing to the windows - would also be less painful if the wiper motors didn't continue to strain at the leash. This issue is the one that seems to be addressed when "frozen" and "wipers" are the query; sadly, this is easily handled manually, and a quick scrape and the basic windshield defroster can handle the issue. There's also
these, designed to cope with the situation.
That low hanging fruit, the frost glazed squeegee stuck to glass, is not what I've been experiencing these last two years. Over a quarter century of New England winters and I've not experienced what I'm seeing now down here in the tropics. All three vehicles have had it happen this year, it's like an epidemic. All visible surface ice can be removed, everything you can get at without disassembling grills and so forth can be cleared and this problem still occurs.
It's one of those design issues that just shouldn't happen. Why, having those motors designed to hope against hope and commit suicide makes about as much sense as making commonly replaced items, such as headlights, difficult to replace. Or mounting sensitive electronic components in an environment exposed to extremes of heat and cold and oils and vibration, such as those experienced in the engine compartment of a car. Or knowing for at least thirty-five years that energy efficiency is a Good Thing and, instead of increasing both efficiency and performance, pretending that you can only do one or the other, and having delusions that the former can only happen if the car is butt-ugly.
