Hi Group,

My 98 Ml 320, with 190k on clock, the cruise control just stopped working in June.
What are some of the parts that could have failed and caused this? I've checked the search engine on this site and read some posts. I've read that the brake switch could have failed but the brake lights work. (one is burnt out)
I've read that improper bulbs could cause the system to not function properly, does this apply to my model?
