Ypu need to know if the ECM is actually seeing the request when you turn the cruise on and try to set it... This may point you in the direction of the issues... The ECM looks at the brake switch, as well as other various info regaurding the Cruise Control... But in order to know where to begin you need to know if the ECM sees you turn on ( or request ) Cruise controll... The Cruise control module under the hood is controled by the ECM...

The ECM for the 88-91 3800 Bonnies is not as adept or as smart as the 94-95 PCM'* and don't tend to notice issues early on...
Do you have any codes... If memory serves there are one or 2 codes that will not set off the SES but could possibly be stored in the computers memory..
Have you checked all of the Vacume lines running to the cruise control module? They tend to deteriorate in a bad way by the time the cars are 9 or 10 years old..
Good Luck
If there is anything else we can answer, please let us know

also ....i don't know if there is something that is supposed to happen when you turn on the cruise besides not having a light...like a sound? could i put the car on jack stands and put it in gear and try to set the cruise and see what happens with something under the hood?...

There is no light, no sound. As for seeing anything under the hood, not sure if you will see anything, except if it works, it will be moving the throttle cable to keep the speed.

ok, well its been a while since i have responded to this thread...
there is vacuum pressure, i pulled the lines of and i heard HISSSS, so, i am gonna go ahead and say that it is most likely a bad CCS. Would my assumption be correct? Also...there is one small vacuum line and 1 larger rubber hose running to the CCS. Now the small one, which i assume is the vacuum line, runs to the vacuum pump, the larger one runs straight through the firewall...i really dont know what that would be. I think i found the CCM, it looks like it is behind the left strut tower...
ok now, i am wondering if i just replace the CCS that everything would just be dandy..because vacuum pressure seems to be fine.
here is a pic of the strut tower..see the black box at the top right corner? what is that? I thought that might be the CCM
