My Son's truck is throwing 2 codes P0542 and P0381.

Dodge Dealer says bad instrument cluster, $1000.00 to replace.

The heater grid cycles on/off (can tell by volt gauge in truck).

Tried to follow a PDF for code 0542 and it shows connections being made to PCM, from my search the PCM is in the engine compartment, is that correct?

What does that have to do with instrument cluster?

Any input is appreciated.
