Multiplex Control Unit

Or

Multiplex Integrated Control Unit

Need to know if those are the only things not work and or if there was any recent work done to the car.

The relay and the switch are OK, so the only thing must be the MCU?...if so, then anubody has instructions video how to replace it? They quoted me for $545 to replace it. I believe that's too much, a ripoff.
