The blower motor is noisy on my 1993 300E (2.8) and I want to lubricate it ,which requires the removal of the wiperarm and the wiper assembly. I did exactly the same on my '86 300E however on that model there is a screw under the flap on the wiperarm that secures the arm. On the 1993 the wiperarm is the newer type without the flap. Can anyone tell me the correct procedure to remove it? I did check my MB paperback manual but it only mentions the older type wiperarm.
Thanks for your help,


Alex
