check your taillights as of 03 there is a circuit board under the rear of these trucks that tell the ecm engine control module if the taillights are functional if one of the bulb sockets has a bad connection or if a bulb is partially burnt or if someone has tampered with the wiring like using the wrong plug on to tow a trailer ,the ecm will not allow the cruse control to function

I know this sounds unrelated but, reset the light and tighten down the gas cap, or buy another gas cap.

I just helped a friend fix his truck that did everything you have stated. (However his was a Toyota)

There are a lot of things that can cause this. Get the check engine light test done for free at a local auto parts chain.

Pull alarm fuse

I would start by replacing the FOB. Sounds to like the electronics inside it are bad. The only reason the horns would go off is if you hit the panic button. There is a slight chance the receiver is bad. But Fobs are cheaper to replace than the receivers. If you have two FOBs and they both react the same, then replace the receiver. Or just ditch the system. The keys (in the door locks) should still activate the alarm system.

Pretty sure it is #25 on the drivers side inside, but I am also pretty sure it is a combo fuse labeled INFO/AIRBAG, and pulling it may disable your airbags.

Have you checked it with a multimeter on the battery to be sure the voltage gauge isn't faulty? If so and it truly falls to 12v and your serpentine belt is not worn out then it is likely a faulty voltage regulator.

you have one of your wheel sensor wires either shorted or a bad sensor.. usually your scan will tell you which one.

Most likely a faulty switch.

Check the fuse for the radio, it might be blown...

I tried to follow the directions in the owners manual. It didn't work. So I called GM. I was told I would have to go to Onstar. Onstar said they could change my bluetooth from Spanish to English, but I would have to subscribe to Onstar.

You may have something blocking the fuel filler neck, or the hose is kinked. ???
