It sounds as if your brake switch plunger is not making contact at the peddle. The way it works is when it's touching, the light is out and, when you step on the brake peddle the plunger from the switch travels outward and turns the light on. ORThe wires are corroded somewhere in the line (possibly at the rear light housing) whereby the brake light wire is powered through an active 12 volt line when the vehicle is running.

check radiator fluid. could be bad thermostat . or possible bad heater core.Switches could be malfunctioning.

Check for a blowin fuse or a defective relay, If there good the blower motor is shot, End will need to be replaced,

Check your fuses. This a common thing that can come up often if you have changed from stock stereo equipment to after market, or just because of old fuses.

Once you locate the fuse box, it should give you a diagram of which fuses go to the different lighting systems in your car. Replace them and the problem should be fixed.

If the problem is not fixed from that, then have your wiring checked throughout the truck.

THis is actually programmed into your computer so you are going to need to take it to your dealer or buy a tuner that is capable of this. Its embedded now and its going to stay until it is manually changed sorry. OTHERWISE you could always put bigger tires back on it and it would look mean!! :)
