Cruise control problems

Hey guys, looking for a little help with the cruise control on my 91 Eclipse Turbo. The light come on but the cruise control does not activate. I have tried activating it over a range of different driving conditions without any luck.
Is there a separate fuse or fusable link for the cruise control? Help. Thx

Have you done any idle spped adjstments latly? If you forgot to ground the white connector to the left of the cruse control it will not work properly.

Jut a thought, well it would be the case in a 2G DSM anyway.
