Cruise Control-1996 CVPI
I am new to this list, and I am in the need of some help. I have a '96 Police Interceptor on my hands that has a cruise control issue. I also have a '96 civvie with cruise control that works. I first followed the troubleshooting tree in the factory service manual which left me scratching my head. All checks came out fine. Swapped steering wheel switches, and speed control/servo unit. Problem still exists. All voltage/ohm reading are in spec with the manual, I have good continuity through the harness, and I adjusted the cable. If you press "Set" button, it holds speed for about 3 seconds and then drops off. Has anyone else had a problem similar? My next avenue to explore is replacing the clock spring assembly, but I don't want to start throwing parts at it just yet.
Any info would be very much appreciated,
