Hello, this morning when I turned my 06 Monte Carlo on I noticed the thermometer on my gauge, my ac, heater, seat warmers, and rear window defroster did not work. The radio itself does, and my center console lights up however none of the buttons are responsive when I press the ones linked to the above mentioned functions. Any chance this is a bad fuse I can replace myself? I called the Chevy dealership and it’s $150 just to get it looked at and asses the problem. Hoping I can fix it myself.

 

That's not all going to be on one fuse, there are several circuits there. If they all went at once, its nearly impossible that you had numerous fuses blow at the exact same time without something bigger being wrong.

Its certainly possible to diagnose yourself - do you own a multimeter and understand how to use one? Its as simple metering the circuits to see where power or ground is lost. As those circuits may share the same fuse box, I'd start metering there.
