Question:

Why do my windshield wipers only work on high?

This morning when I went out to leave for work I turned the wipers on to wipe away a bit of the water left from the snow melting. (The car had been on for 30 min to warm up) The only speed that would work was full blastAlso a new error would be that the driver side mirror defroster isn‘t working either. Any ideas on what could be wrong? And before anyone asks no the wipers weren‘t left on and froze. I‘m always sure to shut everything off before I turn the vehicle off.

Answer:

properly the glaring could be to study any and each and all of the connections and wiring. different then that there are truly purely 3 issues (electrically) to a wiper circuit. The change, the relay, and the motor. The change could reason a topic like this because of the fact there are man or woman contacts interior the change that could positioned on at diverse costs. The motor could desire to be your subject because it may desire to be providing you with a warning that it extremely is approximately to fail thoroughly. I doubt if it may be the relay because of the fact then it does no longer artwork in any respect in any speed. they're the two working or they are not. whether the relay connectors could desire to be corroded as properly. So there is my rundown. sturdy luck.
The mirror defroster might be due to a blown fuse
4 mol of iron + 3 mol of oxygen gas yields 2 mol of rust (chemical name: iron(III) oxide)
Given I live where th'snow don't fall, I would first check the car fuses to make sure they have not blown. This may account for your side morror. It sounds like your windscreen wiper motor may be on it's way out. Worthwhile to check with your car mechanic, if your car is computerised they can put it on the computer machine and fault/s should show up.
