On my 83 300SD the cruise control will not hold the
desired speed. I can use the accelerate function to
get the vehicle up to speed. I can also keep my foot
on the accelerator and feel the cruise control trying
to hold the vehicle at speed until it eventually gives
up.
Yesterday I cleaned and lubed the cruise control
linkages with ATF. Also cleaned the #12 fuse block.
Car had same issues this morning.
I suggest that you clean the connector to the amplifier and the
connector to the actuator, but more than half the time the problem is
cracked/cold solder joints - especially where the printed circuit board
of the amp connects to the connector pins. Rebuilt amps cost $150-200. I
believe that actuators cost about the same.

I think Rusty can supply rebuilts.
