Won't turn on screen is black

Had a bad jump start that fried a few things a few months ago. Replaced battery and alternator, so those are both new, and replaced the 100 amp mega fuse and A/C relays. The truck started and ran for several weeks, but then one day turned the key and it did absolutely nothing...also, absolutely NO lights on the dash display except for the check engine light. Had a friend test with scanner and it can't link with computer. Got a new programmed PCM, installed it, and same problem. I think it's a relay, but no idea which one.
Also, we've noticed that now the brand new battery goes dead quickly, like, in about 3 weeks. I just think that's awfully quick for a new battery to go totally dead. It's as if something is stuck ON and draining it. Any help would be greatly appreciated!

Every morning after about 5 to 7 min the ABS, Traction Control and Brake light warning turns on and the messages Traction Control Fault, ABS fault and brake fault shows up. 4x4 is allow but on 4x4 Lo no dash indicator. At scan tool under Cruse control and / traction control under the engine module I can se TCS short to grown/open hight

All off a sudden ac stopped working an blowing hot air the Freon is full plenty of pressure but compressor won't kick on I checked the pressure valve sensor on the line jumped the plug with a wire an compressor still doesn't work

All 4 power door locks stopped working at the same time. They don’t work with the button, or the remote key fob entry! The owner’s manual does not list the fuse # for power door locks that I could find ! Or could it be something else?

Hello, my van's problem is that the engine starts whenever it wants and, when it doesn't, the anti-theft padlock appears and I have to wait for at least 15 minutes to start driving. The other faster way is to open the switch, disconnect a terminal and connect it intermittently many times, and it then starts. If anyone could help me, I would be really thankful.

Neither the drivers side controls or passenger control works. Where would be the best place to start diagnosing this issue?

Radio went out, checked the AUX fuses and they were all in tact, shoulD I pull radio and check for connection.

I had 4 chevy colorado and they all had the same problem with the horn first its sounds weak and second I have to press hard on the steering wheel for it to sound

Oil is leaking from the vacuum pump

The alarm is locked, the truck do no work, the battery is shot down

No sound coming from the radio or blinkers. No inside sound at all

AC went out so it was replaced for $2400. After a couple days it started letting off a high pitched whistle. Not consistent, but often… the AC starts losing its coolness for several minutes. After a couple minutes, it’s fine.

On my Chevy Colorado 2012 LT model. I have a problem with my horn not working due to the fact that I’m not getting contact on both sides of the fuse. How do I remove the wires underneath the fuse panel to tighten up the clips so I make good contact

Lost key got one made can't get it to program to shut off anti theft replaced everything that I could replace ignition wise

While I was driving this morning I used the steering volume control and the radio/infotainment screen went black with no sound out of speakers

overheating new thermostat didn't help

What color is the power wire in radio

What would cause cruise control, brake lights and left turn signal to not work when fuses and light bulbs are good?
