My 2000 Ram 2500 seems to have an issue not being able to turn the cruise control on. I checked what I could and found a vacuum line that was severed and repaired that but it has a rubber hose and the line is plastic. There are about 9 things that would cause it not to turn on from a blown fuse to a faulty cruise control module and I read somewhere that the PCM sends power to the unit and has to be checked out that way. I would like to repair this myself so if there is anyone who had a similar problem can you please let me know what you discoverd to fix it.
Thanks in advance for the help.

 

If you don't have it already, grab the 01 service manual from here. Have a look at the wiring diagrams for the cruise, (speed control) and make sure you are actually getting power TO the switch, and you get the correct signals back from it when you push buttons.

 

Thank you Hey You. I was going to see if I could get my hands on the shop manual but now I got it thanks to you. This should help me figure out what is wrong and will save me a lot of time and cash.

 

Its not uncommon for the switches on the steering wheel to go bad. You can get new switches from rock auto, and there not that expensive.
