Re: Pulsing/Surging Cruise Control
Mine cuts out on the downhill travel, will not hold below 45 mph. I replaced all the vacuum lines, actuator, brake switch, everything but the control lever on the column (1983 model year only type). That switch/lever was not available until recently, and it is too much to warrant replacement. There is a circuit board in a red plastic box under the dash, but that has to be sent into the aftermarket manufacturer and they are supposed to be able to repair it.
Converting to electric cruise I think makes more economic sense - vacuum is an unreliable method IMHO.
