After initial warm up (ussualy few minutes) dush board control lights and gauges go on and off and after a while everything on board start flickering and after some time all gauges go on zero and control lights are totaly dead.The only way I can revive them is to take off buttery cable.After warm up everything starts again.During all this fun, turn signal control lights and head lights are ok.

Re: dush board lights and gauges start flickering
Indeed a fun one..i suspect a floating ground (poor ground) near instrument cluster causing the anomalies.....headlight circuit and signals are different so this makes sense .... if not fixed the instrument cluster will finally smoke and need replaced i think ...good luck

Problem could be a bad oil pressure sensor or the oil pump is failing. A mechanical oil pressure gauge needs to be hooked up to verify actual oil pressure. Problem could also be a bad stepper motor in the instrument cluster that drives the gauge.
check your door controls, they are known to short out. When you try to boost it after it has died, have you disconnected the battery for a few minutes first? Had this problem with an 02 envoy when the temp dropped below -20
is it the lights of the gauges dont light up or the gauges dont work period? if they dont light up then check the bulbs that are behind the gauge cluster and they could be burnt out i have the flickering prob with my ac hvac controls and half the lights on my gauges dont light up due to bulbs being burnt out i just havent spent the money to get some blue leds to put in there
Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.
I had the same problem some time ago, lights would go on and off, odometer appeared to stop counting at times rpm gauge would work and then not... power steering would off and on work and head lights would blink on and off when in driving light mode (off position).. The fix for me was I had to have the dash computer replaced (about $500). After doing this around 50k miles ago all the gremlins seem to have remained gone.. Hope this helps
