Found a weird issue, Running 15/16 seats in my 13 and everything works but the heat shuts off on both seats after 5-10 seconds. Can connect to the module via AE, but its showing Left Seat Heat Resistance High and Right Seat Heat Resistance High. Any ideas? Was thinking the module may not be playing nice since it a 13.
Sorry I'm just seeing this now. I came in after cleaning up from the blizzard, sat down for a few minutes, and woke up at 3AM. lol
Anyway, the seats I put in my truck were from a 15 Big Horn, so they were heated only. I installed the switch panel and added the option to the BCM so I'd get the soft keys on the radio. But, neither the seats nor the wheel would work. They'd turn off after 5-10 seconds like yours do. I tried a bunch of stuff and couldn't get them working. It was summer, so I just let them be at that time. But, I would try them periodically.
After a month or two I replaced my bezel with the factory 8.4 one. After I finished that, the seats and wheel started working. I still don't know if it was because of the conversion or because I had the battery disconnected for a few hours.
I recently swapped out my driver's seat for one from a 13 Laramie. It worked immediately, and plays nice with the 15 passenger seat too. The ventilated function doesnt work, but that's a different story.
