The windshield wiper assembly on my Roadster just started making ugly scratching and high-pitched screeching noises. At first I thought it was the wiper blade scratching across the windshield but it is not - it is the motor/assembly itself. In looking at Lotus posts, I see several Lotus owners complaining of such a sound and apparently replacing the motor and assembly as a unit. Does anyone know if this Roadster motor and assembly is the same as used in the Elise? If so, is it easily replaceable or does a replacement involve a removal of the brake master cylinder and other parts to get to it? Finally, is it possible that just some lubrication on it would solve the issue and if so, how do I get to it to lubricate it? Any assistance is most appreciated. Thank you.
