Am new to this so hope this is in the right section - apologies if its not!
Recently bought a 1999 Astra Club 1.6 and have been having problems with the rear wiper which only clears the top half of the rear screen leaving the bottom half still wet.
I have replaced the blade with a new one but that has not made any difference.
Could there be something wrong with the wiper arm itself?
Any help would be most welcome
