Cruise control was surging nowno longerworking. which device is the most replaced
Amplifier, Servo, speed control sensor, etc

 

What MBZ model? It is very likely the Servo Control board. It is located behind the panel under the dash. It looks like a rectangular aluminium box. I have 2 removed from a 83 800D from a junk yard.

and have they been tested.

I have the exact same problem.. Aside of replacing the servo are there other steps to ensure its not just a loose wire or unplugged sensor.. I too would be interested in buying one if the simple things dont work.. Thanks Chris

I have an 83 300SD
