W126

I have a 1982 300Sd that I am repairing for my kids to drive. I can hear the wiper motor running but the arms do not move? I know I have read somewhere about a Bakelite piece or something that wears out and it controls the arm movement. IS there a simple modification repair that can be done...AND how do I get to it, and how do I make the repairs.

I am having a meltdown here all the usual suspects are rounded up. My 1986 300SDL (that I have spent more time working on than driving no kidding) is a great car has me perplexed. It started and ran fine one day the next started and idled fine but gives me about 100RPM increase when I push the throttle with foot or under the hood so all the linkage is moving the way it should.

Can someone give me some info on what a reasonable cost would be to replace the leaking rear seal on the transmission of this car. I understand that the tranny must be removed so it is not something I can tackle myself. Plus, there are specialized tools etc. required to do the job correctly.
