Cruise Control

[benzjag]

I just bought a W116 1979 300SD after owning around 25 W126 300SDs!

When moving the cruise lever up, the car will accelerate, but will not "hold". Is this the cruise amplifier?

Any insight appreciated! I am trying to "learn" the W116 chassis!

Many of us have been down that path, and had fixed their units with varying degrees of success.
