Instrument cluster is dark - side mirrors don't move - and ...

[chrisfuture8]

So I think my SUV (actually, I inherited it from my wife) is really seriously falling apart now.

First, the trifect lights come on after a few miles and transmission goes into LHM after a number of miles. I know how to deal with that but now, the instrument cluster went completely dark.

Gas, temperature, speedometer, tachometer, none of that works. All dead.
However, the ABS and airbag lights are the only lights on the cluster that comes on.

The side mirror on the passenger side no longer shifts when put in reverse.
I also noticed I have no A/C now and it's been hot weather in the Bay Area last couple days.

I'm sure someone have had or heard of this happen before so please enlighten me.

Before when the A/C doesn't work, I discovered that root cause was due to low refrigerant and I refill it. However, this time, everything stopped working at the same time so I believe there's something else.

I can still drive the car and gauge the speed by staying with the flow of traffic and I don't drive the vehicle much. But, I definitely would like to get this sorted out as I spent a lot of time and money refreshing all the gaskets in the engine as well as replaced front end suspension components (upper and lower control arms, both axles, rotors, brakes, sway bar links, on and on).

Looking forward to receiving ideas from the collective brain trust.

Thanks!
