does the yellow light come on?remove the small hose on the servo. There should be vacuum their. Remove the large hose and try to blow through it. If you can blow through it you need to adjust the brake light switch. if you can't blow through it, it is adjusted properly. Check the codes by pushing off and warmer on AC panel. When you see all segments light release and write the codes. You may have a cruise control code set and that's why it's not working.

I have a vacuum. I can't blow through the hose so it is adjusted right. The yellow light will not come on at all.

Ok I I got this book at the library to help me out. I understand most of it but I want to make sure I do it right. Here is the diagram for the 1992 Cadillac Deville. I understand how to do the off and warmer then let it go to the 7.0 because I have no codes. I know the cruise lever has to be on. Then you push the brake my data center shows e.0.0. Once I hit the brake am I suppose to push the low and high together. Thanks.
