I apologize, I should have given a bit more details. The whole cluster - including - RPM gauge, Fuel Gauge, Temperature, Current mileage doesnt work when I turn on the ignition. The behaviour is when the car has been standing in sun for the whole day.
I took the car to a dealer and dealer change my speed sensor for 250 $ already (before contacting u guys) so, the fix you suggested has already been tried !
So, in details, when I turn on the ignition (after the car has been standing in sun for the day) the whole cluster is dead. When I turn the keys, I see other lights like SES, BRAKE, AirBag etc. As normal behavior, these lights go away after the car has been started (so, the car starts fine - but all of the cluster is dead). If I take the car to a freeway with this behavior the car starts loosing acceleration - as if there is some power loss, I still have control on Brakes - Steering. All other electronic works fine - AC / Radio / Power Window. Once I slow down, the car regains acceleration. After driving it for 5-10 miles the cluster turns back up - perfectly fine and then everything is perfect ! It doesn't go down again after it has came back up.
