95 caprice signal/cruise control arm

[94HeavyChevy]

my cruise control in my 95 caprice shuts off randomly after it is set at a certain speed. does this mean the unit is broken. i found the unit on ebay for 165 bucks. anyone else ever have this problem or know where to get it cheaper?

Yes. In my '94SS the cruise would randomly drop out for no apparent reason, then would not re-engage until it had been shut off for several hours or the car was parked overnight. The symptom got progressively worse. The cable was adjusted under warranty at 12,700 miles. At 57,325 miles the cruise servo was replaced under warranty. At 61,049 miles the cruise control switch was replaced under warranty, the brake pedal switch was adjusted, and all wiring was supposedly checked. At 86,287 miles the servo was again checked but no warranty replacement was offered. At 108,800 miles the unit was almost totally inoperable. At 114,100 miles I opened the unit and cleaned/adjusted the worm on the stepper and sector gears, checked the clutch operation, and cleaned and verified all the connectors in the servo unit.

At 118,042 miles I I continued the investigation and replaced the suspect servo unit with a salvage yard piece with absolutely no change. I finally determined that the brake pedal release switch was not working consistently. The NC contacts (GRN/GRN wires) tested with over 50 ohms closed. I removed and cleaned the switch of apparent damage from from arcing and contamination and the contacts tested at 1.2 ohms. The unit has been working normally for the last 25,000+ miles.

The point here is that just because you read voltage at the terminals on the servo unit doesn't mean that all the supporting devices are completely intact.

I will definetly check into that then. Thanks for the advice
