Hi,
Hoping someone can help me diagnose and fix this: my wipers work in auto-sensing mode and intermittent mode as expected but the speeds don't work (as I move the wiper control arm upwards) - they just stay at the same (I think medium) speed. I'd not normally care much but I was in a storm the other day, the wipers weren't vaguely keeping up and I had to pull of the highway to let the storm pass.
Does anyone have any tips on how to diagnose this? Should I be determining if I need a new motor, control arm, or a module somewhere?
Thanks
