How about a wiring harness from a truck in a junk yard?

That is what Spaulding does as someone previously said. I did call them and they have something but trying to get part number first.

Having been on (too many) forums for these trucks, cannot say I've heard of that issue until now. Best of luck getting it repaired!

But, are you saying that whole switch bank was intermittent or not operable at all prior to the first replacement of the switch bank and then it worked 100% of the time for a couple months and is now intermittent again?
If so, that seems to me to be either the new switch bank or possibly a bad connection. If the new switch fixed the same condition previously.

Yes on all points. It fixed the issue then went bad. Many variables now. Could even be an open not a short and need solder. Any good shops for electrical in Spokane? And I might just have them replace the switch again.

Here is another point that everyone with a Ram should take note. How is an electrical wiring harness part obsolete in only 8 years? Why would I need to go to a junkyard to find this part? I think I am done with Ram no matter how Cummins faithful I am. If the truck was still under warranty what the hell would they do?

You're out of warranty, get it to a good diesel shop and to heck with the dealer service department.

Name one because I really don't know of any around Spokane. PM me


I don't live in Spokane so I can't help you there. Boise area I'd recommend Big Twin or Gem State if you want to take a road trip.

To me, this really leads to a defective part and not a random short in the harness.
I believe the switch bank is just that, switches, possibly a common power source to the unit. I know it seems low odds that it's a bad part, but the last new switch wouldn't have "fixed" a different issue in the first place.
That's my process of deduction.
Do a little research, but I bet you could have the dash apart and swap switches in under an hour with nothing more than a set of basic hand tools. Think of it this way, the cost of a new switch assembly is probably half of what even a diagnostic charge is from a shop.
Quick search shows a bunch of Utoob videos to walk one through it, even.

Possibility that it's the BCM or wherever the signals are sent to, or the harness, but based on previous replacement solving it, I'm still headed there.

A possibility.
TDR forum, same year truck, same issue, but totally dead switches (not intermittent), even after a new switch assembly.

"Just an update: I did take the truck to the dealer, who was certain it was the set of faulty switches. He did order, installed...and still the buttons did not work. Then he checked for power at the switches and there was none. (I would have thought checking for power should have been step one??) Regardless, they followed the power to a corroded spring type connector, replaced the $1.20 part, charged for 3 hours labour and sent me on my way. All is working."

IMO, get off RVnet and start researching other sites.
I just googled your issue and there is a bunch of info about it.
