95 c220 Turn Signal Problem
 

I replaced the Combo relay
(old part was 201 821 00 47)
(new part 201 821 02 47)
and the wipers and defrost now
work and the turn signals work,
but sometimes make a strange chattering sound
and blink rapidly. Is there another
component that needs to be replaced
or did I use the wrong part or
is the relay defective?

That is the correct relay part number! IS the part OE or aftermarket? many times the aftermarket brands(KAE) JUST don't work correctly.

The part is K.A.E., I guess thats why
the part is 100.00 less than OEM
So I should return it?

Hey, I am having similar problems with my 95 C280...where is the relay located? Thanks.
