On/off switch? Ignition switch? Relay stuck?

Here is a link to wiring diagrams. http://bbbind.com/free_tsb.html

Yes they are the same relay.

Try the power antena wire.

check with your service dealer as GM products have a recall on faulty ignition switches

Welcome to the club .Obama motors . I have read your post .The problem is realated directly to fuel deliverery.You had problems with the EVAP system .Misfire on #8 cylinder . The vehicle is olny 2011 but you have a lot of milage for 3 years . I would check the fuel filter first thing a lot of fuel has run through it .The fuel pump could also be an issue however they normaly last 10 years or so but depending on how much winter driveing you do the road salts they now use are much worse then they use to be as far corration check the connecters to the pump. What I can say is most of these codes you are getting have nothing to do with the problems you are haveing there just side effects of how the VCM .controls information and the air horn had nothing to do with your problem nor did your dome light .The olny other thing could be a problem with the injuction system the regulator or an injector. Try the fuel filter first but it is in the fuel system

They are right .just like a space saver tire in a car . You also should look and see weather an 18 " rim with tire will fit where the tire is stored.

It could be a loose connection or bad button. There is also a minimum speed needed.Try holding the button for at least a second.

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.

You will have to have the ECM read for mileage to determine what is bad. The ECM also records the miles. If the ECM and cluster match, you would have had to put some really small tires on the truck. Different gear ratios could cause this, but should have pop a code. My guess would be the cluster isn't working right. Have it scanned...

Run a fused wire from a "switched" terminal in your power distribution box to the HOT side of your relay coil. Attach the other side of your coil to ground. On the "LOAD" side, which should be a set of Normally Open contacts, connect your live12 Volt on one contact and the other contact should be connected to your cigarette socket. Don't forget to ground your socket as well. Hope it helps you. Write me back if you want more details. Good luck!

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.

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)

huh??

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.

Look under the hood and there is a belt routing on the radiator support.

Yes, you can remove the interior in the truck. It is very time consuming.

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.

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
