Hello: had a new top installed turned out fine, however they noticed that one of the hydrolic lift arms were leaking, so I had them both rebuilt by top hydrolics out of Portland Oregon. They installed them and then the trouble started, now nothing works, windows don’t go down when turning D handle, and the light for the top on the console is blinking. Needless to say, they don’t know how to repair. I searched everywhere in Richmond va and no one including Mercedes will work on this car. Can anyone steer me towards an expert that can repair my too ? I love in the suburbs of Richmond, Va
