I have a 2000 blazer 4wd it is been sitting for about a month now the battery was dead so I jumped it and what I have now is the odometer don't work the gas gauge don't work prnd321 don't work the radio doesn't work I have checked all the fuses everything is good so far I replaced the ignition switch because I had the same exact problem before. I just put a brand new battery in it once I shut it off the prnd321 and the odometer work with the key clicked on any ideas guys.

 

Update now my temp gauge is not working and my high beam indicator is not working also the cd player is getting hot on the back of it.
