One problem ends,another one starts. Wiper motor!

[BLUETHUNDER]

Well it seems lately that there is one job after another. Now its the turn of the front windshield wiper motor.

I have had the usual dumping of the fluid and the wipers acting on there own. I followed someones advice on here and cleaned the module out and applied some silicon spray.Job done!. Now ive noticed that when you turn the wipers on,they hardly move until it slowly gets halfway across the windshield,then it starts to move properly.

Does anyone know where i can buy one outright other than from a main dealer??

Thanks for any help given. Mark
