So I've had this 2000 Monte Carlo ss for a few weeks now and when I first got it, the gauges would run their check and go all the forward and back. I've noticed recently they have stop doing that, wondering if there is a problem here.. and also my temp. Gauge does not move anymore.. it worked randomly for a while and now not at all..thermostat?

 

Is it all the gauges? Check the BCM fuse, I had that problem when I first got my car and the previous owner had an aftermarket amp remote wire connected to the BCM fuse. If you have an amp connected to that reconnect it to your radio antenna wire (forgot color) hope I helped.

 

It could also be the motors to the gauges,mine quit working and i havent gotten them working yet.But i found a better replacement part from another member,you can get these on ebay new cheap!
