give me your email adress via pm, i can email you instructions on how to remove everything back there. also you may want to take t to the dealer to make sure what is wrong with it, looking through the guidlines, could be regulator or back wind ecu. you posted some help about some retros and you said you werent very good on electronics, this is more of a tackle then headlight IMO, to check the motor and other electronics back there. but i work for a dealership, any futher help let me know, i can give you a good deal on the parts you need to fix it too.
fyi if anyone needs stuff like this please let me know, i am nore than happy to help.
