I have a 99 W210 with the ever increasing electric problem inside. Seats, windows etc. I have located the can bus connector near the A pillar and pulled it out, small connector block in brown. I wanted to start removing each one over a period of time to try to find the problematic module as this is what I have been told to do but I could not get the first plug out and eventually it broke. O dear, what to do now? the part that has broke is the small plug holding the first two wires. Any advice please regarding repair and how to remove the rest?
