ive had a search through the archives, but have not found any real comparisons with my problem. basically my 190e has been sitting a while, and when i use the wiper, it will not complete one "wipe" and return to its starting point. it stops at various points aroiund the screen, it sems that the
"park" functoin has gone array, as if i turn it on and off, it will park itself anywhere? does this make sense?

any help woiuld be appriciated

yours
