Dodge Repair Questions? Ask a Mechanic for Answers ASAP
hello, have you installed the switches yet? the reason i ask is the newer dodges are real easy to add cruise control depending on what engine you have. some all you need to do is install the switches.
what engine is in your truck?
it has the 5.7 hemi. I have installed the switches, but no cruise. That's why I started wondering if there was a parameter in the ECM that needed to be programmed. It's at a dealer now, they seem a little confused.
i installed one in an 07 and like i said it was straight forward.
does your cruise light come on out all when you try to turn the cruise on and off?
well i explain my concern now that i know they are from a durango, id have the dealer check the part numbers and make sure the durango calls for the same part number as your ram and the reason why is the newer vehicles use multiplex systems for alot of various different electronics in the vehicle including speed control, now what multiplex is, is the speed control switch only has one signal wire from the switches to the pcm, and the switches change resistance on that wire through various resistors in the switches themselves the pcm sees the different voltages on that wire and knows which request is being made based on those voltages.
it is possible that the durango has a different set of resistors in the switches and that is why your ram's pcm is not seeing the signal.
