Gear selectors on my Rebel's steering wheel are causing only downshift

[shagya]

Since today BOTH gearselectors ( - & +) on the steering wheel do shift ONLY down to LOWER gears.
When I push the +, it takes even the next lower gear also. I had to choose N and then D again for driving towards. Never had that before. I stopped the truck, turned off the engine and started it again more times, hoping to reset the failure, but did not help to solve the problem.
Without manual manipulation the transmission is working well in the D position.
Is it possible to repair by software? Or must I change the unit?
We don't have many professionals for RAM in our country, so I appreciate any feedback.
Thanks

I would start by replacing the switch as it's most likely transmitting the wrong information. The steering wheel buttons work via a communication bus.

Did you try pulling the negative battery post to see if a battery reset does anything, i agree with Crash,it's probably the switch,but pulling the battery posts might be worth a try before digging into the switch.

OK good idea, gonna try it today...
The issue begun after a remote start what I not often do. Maybe this is responsoble for a malfunction of the software.(?)

Remote starting the vehicle wouldn't have caused this problem. If it's a glitch it would have happened any way the vehicle was started.

I'd manipulate the switches back and fourth about a hundred (or 200) times ..in the driveway (truck off). Dust and minor surface oxidation can cause flake-out of switches. Real common on vehicles, esp with switches which don't get used a whole lot.

The +/- switches on my Ram's stalk were the same way. I basically did as above and they've been good for a couple years now. Doesn't cost a dime to try.

The other thing would be (after manipulating the switches), to pull the steering wheel and inspect the contacts, and/or the wiring connector under the steering column. And maybe wiggle all fuses.

So gentlemen! I replay today after just two days without electricity and internet after a big storm on monday which I've never seen before in the last 30 years.

I pulled of the negativ pole of the battery for few hours. The switch on the steering wheel is working well again !!!
Thanks !

Hey, it usually works with computers (did you try turning it off and back on again?), why not a truck?

Thanks for following up.

Even though the switch is working again, open the engine fuse box and push down GENTLY on all the fuses. I bet you find quite a few that are loose. Both my Jeep and my Ram had about 60% of the fuses not completely seated. This has been known to create all sorts of electrical gremlins, especially on rough roads.
