Windscreen wipers stagger on the windscreen and make a screeching

bad switch change it.

try a fine needle and clean jets at screen .i find a strand out of a wire brush great for cleaning them

go to Autozone and they will do it free , if u cant find one, napa auto parts will also do this

new stalk req

Either the replacement sensor the windscreen technician should have fitted isnt connected properly to the glass or it has developed an intermittant fault - quite common with Renaults especially megane scenics and grand scenics....

easy problem to solve. open bonet look at bottom of wind screen you may have to take plastic cowl of wiper linkage. 3screws. linckage will have jumped off ball fixing . put some grease on ball slip on linckage will be tight but will go on job done.

Hi

Increase the strength, and the amount of your windscreen washer fluid, this can help !

Good Luck !

A FixYa rating would be appreciated please !

My 1998 megane developed same prob dont worry its easy to solve! Open bonnet locate w/screen wiper motor lift up the black plastic moulding around windscreen wiper undo 10 ml bolt holding motor in place get a length of wire about 16ins pare off the end of wire wrap around the head of now loosened bolt tighten bolt replace cover then attach other end of wire to chassis or earth wire on battery hey presto everything functions again took me 10 mins and im a chef lol

see if you got any broken wires from your dash to the fire wall,it could be a short between the wires, but get a second opinion,thats all i can think of....

Hope it helps...
