I own a 2006 Chevy Cobalt LT Coupe.

My car has several electrical type problems.

1. The car's power locks don't work properly. I can not lock or unlock the car doors from the button on the driver's side. On the passenger side the car doors unlock when you press the lock button and that's only sometimes or with multiple presses. Today, I started having a problem with the car not locking or unlocking the doors when I put in into park, reverse, drive, or shut off the engine. Previously, the locks have done the thing where they locked and unlocked on their own. I do not have keyless entry for the vehicle.

2. Radio display gets jumbled. This only happened twice where my car's radio display showed random numbers, letters, and symbols all jumbled up together. It also flickered in and out and at one point the display stopped working completely and only came back on after messing with the headlights and opening and closing my door. From what I remember this only happened while raining or after it had just rained. Hasn't happened again in a while but still concerns me.

3. Service airbag light is always on. The other day when I was driving the light was on in the information panel, but I noticed that in the center console where the passenger airbag light is, it was starting to flicker on. Eventually the light went back to being off.

4. Other power & interior features don't work. Power mirrors are unresponsive and the rear mirror reading lamps don not work.

I already bought new fuses and replaced the ones that I thought were causing me trouble but that didn't change anything at all. I also checked the bulbs to see if they were bad. one looked blown, the other seemed fine. I put another working bulb in to see if it would work and that was a no go.

Solution?
So I'm guessing there could be a problem with the ground wiring in the car since some of the stuff half ass works. I wouldn't mind checking on it myself but I can't figure out where to find it.
Help pls?

Under the driver's seat is the ground for the BCM which controls 99% of the stuff you mentioned. There will be about 5-7 wires joined and brought to ground at that point.

Coby7, I can see that you are a very helpful and insightful person in this community and I know you will be a great help to me in the future. Jah :thanks

UPDATE

I fiddled around with the ground wiring under the driver's seat, went through the DIC menu to check the door lock settings, and once again put in new fuse(s).
Nothing changed except my locks are back to auto-locking/unlocking when I switch gears. I can't be certain whether or not what I did fixed it or it coincidentally started working on it's own since nothing else started to work.
