Okay at one point in time my cruise control quit working, about a year ago. Then one day I got to lookin at all the vacuum lines and found one that was broke, fixed it and yay Cruise Control works again

About a month ago I was crawling around under the hood, changing spark plugs and after that my cruise control wouldn't work. Got to lookin around today and did not find any vacuum lines off or anything out of the ordinary, I even took the battery box out and tracked the vaccum lines to that box looking thing that has something to do with cruise control LOL right underneath that batter box and found nothing out of the ordinary. The light comes on when I turn on cruise control on the steering wheel but when I try to set the Cruise speed, nothing happens, any help would be appreciated. I'm lazy and need cruise control lol

 

the servo (the thing under the battery) might be junk. or your set button could have a bad contact.

 

what about the other vacuum lines...any other leaks?

 

yeah, besides checking the servo itself, and the other vac lines and check valves, plus fuses/relays. You can try this https://dodgeforum.com/forum/2nd-gen...h-r-and-r.html

If you have tilt wheel,remove the panels on the column and check for broken wires.
And the brake light switch on the pedal can also be an issue.

 

Yea for some reason I still think I had to have broken a line that I cant seem to find because it worked and then I changed spark plugs, and now it doesn't work. I'll keep searching I guess and if I cant find anything I'll first look into the servo

 

yes that may be the case, i had two wires chafe and they melted. so +1 on that
