Question on Steering wheel radio controls
 

Hi All,
I have an Avic Z2 that replaced the OEM radio. I used a PAC-Audio swi-ps interface to the remote jack to connect the steering wheel controls - and it has worked fine for years.

For some reason, I lost the "program down" switch. I've reprogrammed the swi-ps, and also replaced the switch - neither made any difference. I programmed the "source" switch as program down for now, and that works.

I've posed the question to PAC-Audio, but I figured I'd ask if anyone has had a problem with one the steering wheel control buttons not working.

Thanks
Dave

im in the same boat, but for me its the track advance buttons...both up and down....but it only does it randomly...if i turn the radio on and off it will sometimes work and sometimes not......looks like i will just have to use the touchscreen instead to change songs.....I have the Kenwood

next place i'd start looking is the path the wires run through the steering column. I've had a number of issues in past years w/ gm tilt columns either pinching a wire or wearing out a contact- killing some or all steering wheel functions.
