P38A Shutting down bit by bit

Further to the remote refusing to function, I now have to use the key. the screen on the HEVAC has gone dark, no sign of light at all.I have checked fuses 42,35 and 8 all are good.plugged in Nanocom. No faults are showing. HEVAC is working perfectly,just cannot see anything. yet again I have no idea.

Sounds like the back light bulbs have failed.
Remote refusing to function may be as simple as corrosion of the battery contacts in the FOB. Just had that on my renovation project.

Just because the LED flashes on the FOB, it does not mean that it has the power to transmit.

Check Alternator output, when mine began over charging, the first thing to turn off was the HEVAC display....
