My cruise control does not work at all. I can press the buttons and the light doesn't even come on on the guage cluster. Any ideas? Its a 2003 with the hemi and i've done that torque management mod where you cut a wire to the computer.

It sucks when driving across the desert towing a boat without it

 

Did it start happening RIGHT AFTER you did the TMR mod???

 

Honestly, i couldn't even tell you. I did that a long time ago and my cruise hasn't been working for awhile either. So I don't even remember when it stopped

 

NVM i fixed my own problem, it was the TMR mod. I just plugged the wire back in and it works fine. I forgot what that mod actually did but i'm glad it works now.

 

Actually I lied, the cruise stopped working again. It only worked right after I put the TMR mod back to stock. I shut the truck off for the night and it wasn't working this morning. What could this possibly be? It seems like a computer glitch but I have no idea.

When it was working last night, it worked perfectly. I turned it on and off a few times with no problems. Now nothing, the light won't even com on, on the dash.

 

If you got the wire hooked up again try unplugging your battery for 10 minutes and try it out again

 

I have already tried resetting the computer. I pulled the #19 fuse and turn the key ignition to the on position and it still doesn't work.

 

OK, but if I get this right, you owe me a six pack of beer.

You may have lost vacuum. I had this one on a Ram owned by a young lady that I fixed about three or four years ago (and I got a LOT more than a six pack of beer out of it, LOL).

Check this line:



Look for either a hole or even a kink in the hose and also make sure to check the ends for tight fit too.
In this particular case, it was crimped and the cruise worked very intermittently, more often it didn't.

 

My cruise has not worked for 2 weeks. I have a 2008 with a hemi. I checked the vaccum line and I saw no crimps or cuts. What else could it be?
