NEWBIE HERE, excuse my ignorance. Okay, I just acquired this 99 Dakota SLT 3.9 V6 with 4 Wheel ABS. The cruise didnt work but the Brake light was on until I jacked with the parking brake pedal lifting it so the Brake light went out THEN THE CRUISE WORKED FINE. Today the cruise stopped working and I noticed the Tach wasnt working either, but I cant recall if it was working when the cruise was also working (just got the truck remember). I suspect the tach not working is also causing the cruise to not work but I just dont know. The horn and turn signals and lights and gauges are working its just the Tach and Cruise that arent other then I got gas today but when I restarted the truck the gauge showed empty until I shut the truck off and restarted it at which time the gauge correctly showed full and cruise worked then at least, but im unsure if the tach was working then or not??? But its NOT now grrrrrrrrrrr

Does tach not working make cruise not work?? Any tips on fixing the tach other then take it to my mechanic with his Snap On Diagnostics???

my truck was doing strange things like yous. What I found was a broken wire under the steering wheel from using the tilt wheel

 

Thanks, I'll take a look. So is it true the cruise cant work unless I get the tach working???????????
