2003 clk coupe
blinking window switches
Thanks to everyone on this forum. I have learned so much about my wifes ( new to her) 2003 clk coupe. This is my first post. Hopefully someone can help me figure this out. Tonight I was driving and noticed that the window switches and seat memory control on the drivers door panel was flahing every second or two. As far as I could tell, everything was functioning properly. The instrument cluster showed no malfunction. I've search and searched for a cause/ solution, but can't find an answer. Any ideas?

NO LONGER ACTIVE
As far as I know, there is no valid reason for this. Those lights are activated by the door control unit via a CAN bus signal. So, maybe the control module is going bad, or maybe there is a loose connection on a wiring harness inside the door (between the control unit and the switches).

Checked connections, unplugged them sprayed contact cleaner, reconnected. Blinking lights persist. Now, window and side mirror have a mind of their own. I'm 99% sure that door control module is dying. My part # is 2098201326, but I can only find replacement part #'s 2098201926 and 2098202126 (ebay). Will these work? I checked EPC and only part listed is 2098202126. Internet search showed 2098201926 superseded 2098202126. I don't want to buy incompatible part. Thanks for the help.
