Cruise Control doesn't work?

I am bleeding my brakes today. If I get time I will try this today if not I will do it tomorrow and write you back. Thanks for your time and help.

Ok I tried this I pushed the off and warmer betton and then I pushed the low fan speed button all that came up was p25 and then lower. I did not start the car. I just turned the key and tried it. Did I do this right or do I need to start the car. Thanks.

I went back through it and it went down and the last thing was p something. I think it was p.01. Then it jumps back up to p 25 again.

I used the hi button and it came up with E.0.0 and it went all the way up to 12 I think. What it did on one of them was you could here a click that was coming from the compressor. Another one was pushing the throttle down on thecircle and the circle would turn. I looked all the way through the computer and could not find the cruise control. Any idea. Thanks.

Maybe I am doing it wrong. Here is what I am doing. I hit the off and warmer button. Then I hold the low button then it comes up with p.25 and goes lower to p.1 or p.O then it goes back up to p.25 again.

Sorry I meant to ask you do Iuse ac or dc volts. Thanks

Ok I just did it on dc volts and it came up with 00.2 or 00.3mv at the end.

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.

Yeah the brake lights work. The problem that I am having is that the cruise control system does not work at all. The light in the display use to glow orange and then when you set it it would glow green. The lights dont glow up at all and when I set the cruise speed it does not set it at all.

I have a digital voltmeter. What do I set it to volts dc or ac. What switch do I pull out the turn signal switch that attaches to the collum. It has the cruise switch on it to turn it off and on. Thanks.

Ok so I was looking for the brown wire but could not find it. Here are some pictures maybe I am looking in the wrong place.
