I’ve owned this del sol for nearly two years and the cruise never worked and I’m hoping to get it working since I do a lot of traveling for work.
I've tried a different module and main button from a wrecked parts civic I’ve got and nothing seems to work but I’m unsure if the parts I’m using worked I the first place.
how do I figure out where my problem is?

 

Do you have a copy of the factory service manual? There is a troubleshooting guide for the cruise system in the manual.

A common problem is that the little plastic stopper on the brake or clutch pedal crumbles due to age and falls out. This will not let the cruise control work, since it thinks either the brake or clutch is constantly depressed.

 

I have a Haynes book on it would that have the trouble shooting in it? Thanks

 

I doubt it will have the detail that the Helm manual will have, but you can look.
