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.

Ok so I pulled the clip out and turned the car to the on position and the gray wire had 12 volts to it. So I pushed the harness back into the computer.

If the Orange light does not come on, you would need to remove the meter cluster to check the bulb and wiring.

Ok I just did that funny thing happened. I tested the white and gray wire that would plug into the information center. I tested the two wires and their is no power going to those two. The two wires would be the ones that light up the cruise control light. If you test the white and gray wires together their is no power. If you test the white wire to the body of the car it has no voltage. If you test the gray to the body it comes up with 8.5 volts.

How do I test the light bulb itself to see if it is good.

Find a power wire. Run a jumper wire from a nown good power wire to the gray. Does the lite go orange then.

Jack the front end up have someone go over 30 mph and set the cruise. Using a test light at the servo seleniod check to see weather your getting power to the seleniod when u set the cruise.
