Hey guys! I'm hoping someone can help me troubleshoot an issue I'm having with my cruise control not engaging. I press the cruise control button on the dash(it lights up), I press the set button and the cruise control light on the gauge cluster lights up and stays lit, let go of the pedal and nothing happens...doesn't maintain speed or anything. I tried pressing the Accel button and nothing happened either. Here's what I've done so far to troubleshoot the problem: I've replaced the solenoid, checked for vacuum pressure(it's good), the brake light switch(works fine), checked cable tension(fine), checked all the fuses(good). Is there any other troubleshooting I could do to diagnose the problem? Any help would be greatly appreciated!

Thanks again!

 

Nice Cb7, have you tried the relay, or cruise control switch and set/accel switch.

 

yes, i have tested them all an they seem to be working as intended.

 

good most likely it was what I was afraid of a bad wire harness. all it takes is 1 short to run a lot of things. just like all the other cars. I say that cos mine use to have a short and believe it or not it was messing with transmission, electrical part of the transmission of course. I'm asking buddy of mine I get back to you does electrical for cars.

check that first

 

Just me but if it "sets" but won't hold (both lights come on)....I'd be checking the vac canister and hoses.
