I see where there is a switch,but dont see the light lens anywhere.
Can the cruise amp be repaired or tested? How? I can get a used one for 150.00.
89,000 miles paid 5900.00 These are the only non working systems found.
Thanks guys.

MB's didn't have an under-hood lamp..the switch is for the alarm system.

Many repair shops have cruise control testers for MB's.

Do the brake lights work?
