I have an intermittent problem w/ my instrument panel that is becoming more frequent. The oil pressure and tempurature guages die; the VSC off warning comes on and flashes and the Auto LSD symbol (car skidding) comes on in the far left cluster; and the ABS warning light comes on. and the Outside Temp next to the clock goes blank. Until now this has just been a nuisance. But, I just found out that when this occurs the 4WD actuator switch doesn't work and I have no ABS (so a safety issue in the snow). There must be some common component for all of these functions. More than just a fuse; ? is it a relay? Is it something that can be fixed easily DIY or do I have to go to a mechanic or dealer for service?
