Exclamation TEMP/HVAC no longer working (radio works)

Hi all, I have a 2006 G35 Coupe. A few days ago, all of the temperature controls stopped working. There is no temp displayed by the clock, and the heated seats do not work either. However, the radio still works. At the same time, the gear of the car is stuck in 'park'; the only way to release the gear from park is to use the shift lock key.

Does anybody know the issue or any suggestions? Thanks in advance.

That previous post was almost five years ago.
The FSM for your vehicle would be a good place to start

ATC Page 33 has a diagram of the control system.
Many points of possible failure.
Has your vehicle gotten wet lately to cause corrosion anywhere in your wiring harness?
Good luck

thanks for reply telcoman, I’ve looked at wiring and all the obvious things, not sure if this could be the problem with board behind radio like the common problem for climate and radio issues, expensive fix if not the problem

Time for the 6/9 year update, did anyone have the solution for this? 2 blown fuses in panel replaced and IPDM fuses are good. A/C and clock display/controls inop. Seat heat doesn't work.

Everything was fine until I turned on the A/C the other day.

Possibly the A/C auto amp. Are both heated seats not functioning?
