i have a 1999 c280 sport. i am trying to replace my wiper motor. i have everything off and can see the motor and see the 3 bolts on the bottom of it, but how do you get under the motor to remove the bolts, there is not much room to move. what size socket is it? any help would be great, because i am trying to swap the core out monday and i have to work all weekend. meaing not much free time. thanks everyone for the help in advance.
