This sounds like a fault in the FEM .. which needs to be read by a NGS tester or equivalent !!
INSTRUMENT CLUSTER
Instrument Cluster Module (ICM) is a Hybrid Electronic Cluster (HEC). Vehicle electronic functions are divided into zones. Instrument cluster, Front Electronic Module (FEM) and Rear Electronic Module (REM) use Standard Corporate Protocol (SCP) communication network to transmit and receive information. ICM communicates with FEM, REM, ABS/TC, PCM and other modules over SCP bus to control gauges and warning indicators. For standard or optional instrument clusters identification, see Fig. 1 or Fig. 2 .
Instrument cluster and panel lighting system provides dimmable backlighting to following components: instrument cluster, headlight switch, front climate control assembly, auxiliary climate control assembly (if equipped), audio unit, Rear Audio Control Panel (RACP), message center switch assembly (if equipped), front ashtray, overhead console, speed control actuator switches and traction control/reverse park aid override switch. Front power door lock switches and front power window switches are non-dimmable.
