93 Cruise Control

The cruise control has never work since i got the car 7 years ago. When you push the cruise button nothing happens, not even a click of electrics trying to work.
I have read on the various threads that there are multiple problems can interfere;
Vacum
Brake Switch
Cruise Module
Cruise Relay
Servo
With the exception of Vacum Hoses which would be the most likely problem part?

I am at the end of finishing multiple projects with my 93 coupe with greenwood package including engine rebuild with comp cam, roller rockers, AFR heads, 36# injectors. It is now in for painting including greenwood scoop, and hood vents.

Thanks
Ken

Here are a couple of links to sites that may give you the info you need. They helped me fix my cruise control, which had the same symptoms.

In my case it was the 'set' button itself that was not making contact. You can check the cruise switch functions with an ohmmeter by unplugging the under dash connector and moving the stalk switches to their various positions while checking for continuity. Also check the brake and/or clutch switches the same way. Good luck!

You can buy one that will do the job for less than $5 on sale at Harbor Freight. Look for their coupons! A flashlight battery powered continuity checker will check out the switches, Just make sure you the ground cable on the car battery is disconnected!
