There is a bulletin to check for an unplugged ambient temperature sensor or open in the circuit. If all is good the ambient sensor is faulty.
#PIC6215A: AC Inoperative and/or Ambient Temperature Display Missing from the Radio - (Sep 14, 2018)
Subject:Â AC Inoperative and/or Ambient Temperature Display Missing from the Radio
Dealer to isolate and repair open circuit to the ambient temperature sensor.Â
Use GDS2 to check ambient temperature in the IPC data.
If it reads -40 there is an open to the ambient temperature sensor.
This leads to the radio not displaying a temperature and AC is also inoperative
Check for unplugged connectors or damaged harness to the ambient temperature sensor.Â
As for the steering wheel controls I would suspect a faulty clock spring.
