C240 Multifunction Display Trouble
2001 C240
I had this car detailed two weeks ago. When I picked it up, the multifunction display no longer worked. Nobody could figure out what went wrong. A few days later, vertical stripes appeared in the display, and on the next start, it worked perfectly. The next start, no go. Then, again a couple of days later, I got the stripes and with the next start, a normal display. Since then, however, occasional stripes, never a normal display.
I took the instrument cluster out and checked the ribbon cable as a member here suggested in a post. No obvious problem there. I tried to check the rear SAM and front SAM, checking fuses, relays, and the computer to look for water or moisture. Everything dry. I got one normal display for my trouble, plus now a persistent SRS error and the AC no longer turning on. I am afraid to try anything else.
I have been unable to find out what drives the MFD. My local shop had no advice other than they had never heard of this problem and maybe water got where it should not have, which does seem likely, not that I have found any moisture.
Anyone have any suggestions? If not, next stop Just Answer or a local shop.
Thanks
