When I first got the car it work and now it doesnt... have had the car worked on by mechanic where its was taken off but cant swear its his fault.....

 

what year and what size engine.
standard or automatic

 

1994 stick and swaped out d15b

 

someone else may have to help.
my book only goes in 91.
but if it the same, then check the vacuum hoses (it runs off of vacuum) that go to the system.
but first check fuse and then the relay

 

ya first of all... check all the fuses....

 

Here is most of the possible problems if your cruise control doesnt work...
Blown Fuse
Short or open in the cruise control circuit
Faulty brake or clutch switch
Leaking vacuum circuit
Faulty cruise control switch
Faulty stepper motor
Faulty transducer
Faulty speed sensor
Fautly cruise control module

hope that helps

 

damn....good luck with all of that, lol. im glad i dont have cruise control.
