Electronic issues after battery change, HELP!!

[sight_life]

2017 Chevy 1500 LTZ

Two weeks ago I drove home from work and turned my truck off while I went in to get my kids. when I came back out the truck would not start and acted like the battery was dead. I jumped the truck and noticed I had lost all saved data on the radio. I let the truck run for about 30-45 minutes in order to let the battery charge as I thought it was dead even though I had no issues before. I came out the next morning and the truck would not start again so I went and got a new battery and replaced it. The truck started just fine but now I have other issues, the radio does not work, the passenger side of the truck is dead, the HVAC changed temp but does not kick on, door locks do not work and the drivers side head light does not come on. I have torn my truck apart and replaced 5 blown fuses, checked the HDI connections, pulled and visually inspected all fuses possible, disconnected the battery and let it sit in hopes it would reset the BCM with no luck. I am at a loss, I am afraid to take it to the dealership as they want to charge me $145 to diagnose it. I have read a lot and things are starting to come back to the BCM from my research. Can someone please help me before I drop a shit ton of cash I don't have nor need to spend especially during these times. Also the truck runs and drives fine minus the electrical issues listed. 

 

Thank you in advance for anyone that helps.

Could be a dumb question, but when you jumped the old battery with another vehicle, did you follow the instructions in the owners manual?

If not, there is a chance you may have hurt some equipment.

I had the same problem, brought it in and they wiggled the battery terminal connection, tightened it more, wiggled the connection, tightened it, and all the sudden the fan, radio, and blinkers turned on.  To fix the passenger side you need to hold the driver window switch down for 15 to 20 seconds, then up for 15 to 20 seconds.

I had the same exact issues after changing my battery.  I ended up disconnecting the battery and let it set overnight.  I got up the next morning and reconnected everything and all of the problems were gone.  Everything is back to normal now.

Having the same issue in a 2017. Combed through all fuses and none are blown. I disconnected the battery in hopes the computer will reset. If any of you found a firm fix please let me know.

I had the same problems stabilitrak, airbag, no radio, passenger side windows not working. Mine was a unplugged connection near the positive cable at the battery
