Another cause of windshield wiper failure is a bad relay. Every set of wipers has a relay that enables the wiper to move or “park” without exerting any effort.
Relays for automobiles resemble plastic containers and plug into a precise spot on a panel under the hood, close to other switches and relays that are already present.
If your relay is malfunctioning, your windshield wipers might park but not turn off or they might park but remain in place even after you think they have been turned off.

In the post, he also claimed that because the metallurgy is built to withstand this force, leaving your wipers on does not wear out the springs. The yield strength and dynamic range of the spring are not being exceeded by the raised wiper arm.
Elliot arrived at the conclusion that it boils down to convenience and preference after sifting through the available information.
