Mechanical help on a '93 300E Benz please!

Hi all, I'm new in the forum and just bought my first Benz. It's a 1993 300E. When I turned on my windshield wiper, it does not move. I can hear the motor running, and can move the arm back and forth across the windshield by hand. I was told there was a nut inside that has come loose, and needs to be tightened. Can anyone tell me how to open the metal shell covering on the outside of the windshield where the nut is located? Any help would be greatly appreciated. Many thanks in advance.

Hi Megan, I can't say whether the 1988 300E works the same as my 2002 CLK, but here is how my cover is removed:

I loosened the lower cover by spreading the two release tabs. The red arrows point to the tabs. However, on a CLK, the lower cover cannot be removed with the wiper arm in place, and the lower cover need only be tilted to lube the mechanism. There is no "nut" to get loose on mine - the second photo shows what it looks like under the cover on a CLK.

BTW on a CLK (and I believe a W210 E-class), the mechanism has to be lubed or it will eventually run dry, start to run slow, start to hesistate in certain places, and then the motor will burn out. It's another one of those services the dealer does, that are listed in the WIS, but everyone ignores when they do the maintenance themselves or farm maintenance out to Joes Taco Bar and Mercedes Repair.
