hi everyone

has anyone every heard of the rear wiper not clearing all of the window in its curve

the car had been left for several weeks, when i got back into it i tried to clear the rear screen only to find that the middle secton of its curve, if you imagine a clock on the rear window, it stops clearing and seems to leave the screen at about 11am and and doesnt clear again until about 2pm

any ideas

thanks

Michael

I think you will find the 'elbow' of the wiper arm is seized and needs lubrication . The arm is pushed 'out' slightly at the zenith of its arc and is not springing back in against the glass lower down .

The rear screen is not flat so the arm does need to spring in and out .

it may also be a little bit bent. mine was (if someone leans on the wiper it will bend it flat too much). careful re-bend may fix it

after several days or rain and a little use the rear wash wiper is back to fully working, good old wd40

thanks for the tips
