Have you checked under-dash fuses 15 and 24, as well as under-hood fuse 42?

I have checked all of the fuses that are clear ones under dash and hood

 

Doing the input tests detailed in my post above should identify the problem.

 

ok thanks.. i knew the cruise control unit box was somewhere in the car.. I'm still trying to figure out what the big box thing is that is in the trunk on the passenger side my lx didn't have that..

 

 

If it's a manual transmission, the clutch pedal switch is often the problem. The lower switch will drop out the cruise control (or prevent it from engaging) when it detects the pedal is pressed even slightly. Check that the rubber pad on the pedal arm, which presses the switch button when the pedal is all the way up, is still there.

 

are these diognostics the same for the 96 also?

 

Not sure. You can check the 96-98 manual at the link in my signature.
