Help I replaced the wiper blade on my 1986 190E and now the arm won't go back down. It's been difficult to put down before but now it's really difficult. Is there a special something that you need to do to get it down?

Thankyou in advance!!!

you mean the return sequence of the wiper arm to its park position
or
the wiper blade cannot lay flat on the glass?

 

Hi there,

it won't lie flat back onto the windscreen.
