CADILLAC DEVILLE CRUISE CONTROL PROBLEM

1992 Cadillac Deville • 135,000 miles

Hi I am looking at a chiltons manuel to diagnose a cruise control problem. I reposted sorry. But Is a speed sensor on the 1992 cadillac deville related to the cruise control. I have checked the fuse it was good. Their is no leak in the vacuum. I changed the cruise lever out. I checked for power it has power. I bought a servo on ebay that was supposobly in working condition. Where is the stepper motor located. From the sounds of it. It is the thing that attaches to the throttle cable and the cruise cable. What is a transducer and how do you test it. Also is their a way to test the cruise servo. Thanks.

U needed to do what khl said. Test for power with key on on the pink wire and ground on black. As simple as that.

Ok so I just did this a few seconds ago after you posted I put the positive on the pink wire and the negative on the black wire. It showed 12 volts exact on my volt meter with the car on the run position not started.

Go to 7.0 then turn on the cruise it should say 7.1 hit the brake 7.2 set button 7.3 resume 7.4

Ok so I am going to turn the car to the run position and do the off a warmer button and let it go to the 7.0 then turn the lever on and it should go to 7.1 then hit the brake and it should go to 7.2 then hit the set button and it should go to 7.3 and then hit resume and it should go to 7.4 is this correct or do I have to start the car when I do this and drive it or just start it or just the key to the run position. Thanks.

Key on this is a switch test. It tells u if the cpu is receiving a signal. Sounds like that servo is ng.
