INstrument cluster no function; HELP!!
 

As i was driving my car last night the aircon compressor indicator light suddenly lost the yello light (and presumably) the compressor's not working as well, the blower however is working.
As for the insturment panel, as i was driving, the fuel gauge, temperature, tachometer and speedometer were on the "zero" level as if the engine was not running.
The warning lights were also off when i was cranking the car.

Help!
