UK Car Repair: wipers, motor assembly, vertical position

Question
hi christian. i have a vectra 04 plate and my wipers are doing its cycle ok but stop in a vertical position any ideas

Answer
its either the wiper relay or wiper motor assy.

usually this problem is  a fault of the motor assembly. diagnosis is more expennsive than both parts so change the motor as im 99% sure its that. the wiper relay is very cheap but unlikely with the symptoms given.
