I finally found a set of heated power sport seats for my 07 335i, which had sport seats but no heat.

I put them in, and to my surprise the driver's side just worked with no intervention. No luck on the passenger side.

All of the other functions on the passenger side work - all the power functions work, no airbag, etc. Just no heat!

I looked for missing fuses and added what seemed to be missing. Still nothing.

I've got INPA and a Foxwell that can't see the passenger seat module. HELP!
