Rear wiper woes
 

the rear wiper on my X5 sometimes packs up, it will work for weeks at a time and then when its next raining it will work for 10 minutes or so and then pack up. when i go to use the X5 again later in the day it works again, its starting to get annoying:mad:, any ideas

What year? Sound like a motor problem or software.

build date was Oct 2002
