crazy wipers

[Davidkroneberg]

good day...

i have a problem an i need help:embarrest:

my wipers for some reason, when i switch on the ignition, the wipers
move half way up the windscreen... i continually have to get out my car an manually move them to their starting position...an when it rains they move down first then up...i even went as far as to(while the engine running) remove the wipers an put them on,to how they should be.but they then smack into the rain guard(the black plastic grill) ..

need some help :blink:

thanks
