Hello All,
New member here but been reading the comments for awhile. I have a 1999 C280 Sport that turns out has a Signal Aquisition Module different from what everyone else seems to have. I purchased part # 201 821 00 47 which is what I read that I needed because my wipers work whenever they want to and when they do work they "jerk" across my windshield. My emergency flashers (4-ways) quit working and my turn signals flash extremely fast. all of this happened at the same time and i thought that i needed the above part number. $200 in labor later and a part that I don't need (because there isn't one on my car that we can find) my mechanic located the SAM with the following part number: 019 545 56 32. When I type this into the search on FastLane it cross references automatically to 022 545 53 32.
What I need to know is, does this control the three or four things that I listed above and if so, does it have to be programmed by a Mercedes dealer upon installation or is it a plug & play like the #201 821 00 47 that doesn't fit my car?
Thanks again for any help that you can give as this is getting expensive quickly!!
