Both front and back wipers are not moving, happened after I scraped some ice off of my windshield. I have tried on all three speeds, as well as trying to use washer fluid to no avail.
when copper is put through a solenoid (coils of wire twirled connected in a circuit) . the relative motion of the copper moving through the solenoid will cut the magnetic field lines and will result in an induced current to the wire. So electrical energy will be produced yes but only while the copper is in motion.
Since both front and back wipers, as well as the washer all went out, it can't be a motor, switch, or bushing. It has to be a fuse. The suspect is #5 fuse, starting from the left of the fuses.
Wipers are designed to wipe rain water and wash the windshield, if the windshield is loaded with snow or froze it's a little difficult on the whole thing that works the wipers, that is what i have an understanding of ththat'sappening with your wipers, whilst you turn them on which you could hear the motor running however nothing is taking place because of snow or ice construct up on the windshield, adequate there is a bar/shaft or rod not certain what it's called, it goes from one wiper to the other that bar is hooked up to an additional bar that runs to the motor, the shaft protruding of the motor has an arm about 2 lengthy and has a ball on the top of it kinda like a trailer hitch ball but about the size of a small marble, the shaft that connects to the ball on the motor have got to have popopped off the ball,or whatever broke just like the ball or the shaft the ball is connected to, you on no account acknowledged what kind of auto you could have, those constituents have got to accesable one way or the other, the panel behind the hood with the louvers on it if you'll find screws or clips jogging alongside the front of it from fender to fender that you may best see it with the hood up, if that is not detachable you then ought to entry it from beneath the dash, from now on whether it is snowing or iced up before you flip your wipers on pull them far from the windshield to be certain there not caught on the glass and eliminate any snow earlier than you turn them on all that further stress will reason them to weaken and making a knocking noise hope this helps you excellent luck!
I would suggest it is a bad wiper switch. Internally, the switch is a copper slide that moves across copper contacts. Given the age of the car, and the fact that it stopped working in freezing conditions, I would suspect the contacts are burned on the copper slide inside the housing, or, the slide is broken. You could take the switch apart and clean the contacts, but it would better to replace the switch.
