Everything works on my car except the windscreen washer pump. I disassembled it and found that the small impeller in not rotating even thought the motor functions correctly. The impeller has a small plastic insert in the center hole with a flat which slides over the shaft of the motor allowing the motor to turn the impeller. The problem is that the flat has worn round and now the shaft rotates but can not turn the impeller. This part is tiny but critical.
Has anyone found a fix for this problem?
