I have a 2001 Monte Carlo SS. Out of no where, my instrument panel cluster and radio stopped working on me. I have an aftermarket headunit and im not sure if that could cause it to do this. The lights work behind the gauges, but all the gauges stay at 0 and the overhead info center just has - - for all the info on the car. Occasionally the gauges will work for a second and go where they should be but then quickly freezes up and just drops to zero, which makes me think a loose wire possibly? The radio isnt even turning on. Any help is appreciated, thanks

 

Anyone? Please?
