Good morning, i need some advise on where to look, i have read a previouse customers problem and it matchs mine down to the T

When turning over my car to start, none of my electrical panals desplay mileage, fuel or rev counter.....the car will turn over and then stop with in seconds after turning the key.

It was sugested that it was a common fault to do with the heater control panel, the earth wire would melt to make the "bus" communication 12volts...what is the meaning of "bus"?

I have had problems with no heat coming out of the normal vents just from the top dash vent only for quite some time now!

it was suggested by removing the heater panel which has 4 screws you might be able to find out if that was the problem, is that the heater panel where you turn on the heat inside the car? Forgive me for being stupid..im not a whiz about cars, i just drive them.
