Because they are BROKEN
As I work on Boeing 747's, I can confirm they do have Windscreen Wipers.
Probably a blow fuse, this may fix it: http://www.norton42.org.uk/389-broken-windscreen-wipers-on-a-skoda-fabia.html
faulty switch
If your rear windscreen wipers on your Citroën aren't working, it could be due to several reasons. Common issues include a blown fuse, a malfunctioning wiper motor, or a problem with the switch or wiring. Additionally, check for any blockages in the wiper mechanism or issues with the wiper blade itself. It's advisable to consult your vehicle's manual or a professional mechanic for a thorough diagnosis.

Its Obvious That The Wipers have Work Hardened,the best solution is to replace them...it also helps to clean your windscreen with vinegar
it could either be a fuse a relay or the wiper motor may have broken/worn out. s autos
There is an optical sensor (looks like a small bulb) mounted where the rear view mirror is stuck to the windscreen( on the inside), raindrops build up obscuring the sensor the wipers are the triggered
why don't the windshild wipers work on 1995 ford countours. their is no power to fuse box or wiper motor.
Check the fuse for the wipers. Otherwise the wiper motor is probably done for.
sounds like a short to power somewhere in your wiper control module, and or relay circuit. well just get it check by your nearest auto dealer. Next answer: Why would you need the windscreen wipers on when the vehicle is off? I don't think windscreen wipers work on any modern car that I know of with the vehicle engine / ignition switched off!
