Ok so i have a 2.0d x3 e83 and the wiper linkage broke off due to ice and snow.. so i have taken out the old broken one and waiting for a new one. Question is: do i have to reset the wiper motor somehow when installing the new linkage? The linkage broke when in use and stopped like in the middle of the windshield..
And they went down a little before they went up again. My worries is that when installing the arm again they will go down in the bonnet if you know what i mean..
