Hi All!
Thanks in advance for any advice.
2020 Jeep Wrangler JL owner.
Installed new steering wheel/harness/paddle shifters

Currently running Tazer mini that was upgraged from the Tazer Lite
Paddle shifters are working as expected but my radio controls (buttons on rear of steering wheel) are not operating properly.

Volume up button (rear wheel rt top button)makes volume go down
Song skip buttons (rear wheel top/bottom button) does nothing
If I press rear wheel rt top and bottom button at same time the volume goes up
If i press rear wheel top and bottom button at the same time: song track will advance
In a nut shell, the rear buttons seem to be transmitting data but not as they should.

Tazer is running newest firmware
I do have a PacAudio AP4-CH41 (R.2) for after market amplifiers if that matters

I've checked the new steering wheel electrical harness countless times
If I have to pull this wheel off again, I'm going to scream....

Any troubleshooting ideas?
Any advice or thoughts are welcome.
Thanks so much for any help.
-Troy

Check for bent pins at the paddle connectors, I had one of the cruise control pins bend and cause me issues when I did the install the first time.

Thanks for the suggestion rharr.
Took apart wheel and check all connections once again. Everything looks solid.

I unmarried the tazer and put old wheel and harness back on just for the hell of it and radio controls work great.

from what i can gather I'm dealing with these possible problems....
-a possible software glitch
-a possible paddle shifter harness problem

I'm about ready to just install the new wheel with the old wheel's electrical harness and just ditch the paddle shifter mod.

The properly functioning radio controls mean more to me than the paddle shifters at this point.
Frustrating.

I wonder if I got a bad paddle shifter harness or
A bad paddle shifter/radio buttons

Considering both side rear radio buttons are not operating properly, I'd assume its a software glitch.

This is just silly at this point....
FML....

Do a continuity test on each plug on the harness and then one with the switches plugged in, each button should be contact switch. I used jscan to activate my stuff

This can all be done on the bench no need to pull the wheel off if the harness is off.

Radio controls do not require any sort of new activation

Finally got it working.
I replaced the phone button module on the wheel and everything started working.
No idea how or if that’s what did the trick, but we’re good to go now!

At least the end result was a success...

Just for the record, it appears the problem was related to a faulty phone button module in the wheel and NOT the Tazer or wiring harness.
Thanks rharr for the trouble shooting advice!

What do you think of the new wheel!
