First umplug the heater motor. If is doesn't blow, replace the motor . If it does, you have a short in the wiring.

You probably have a bad motor, and, you need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.

Determine which circuit is involved and then troubleshoot that circuit You should take your truck to Autozone and have them check the charge on your alternator, they do this for free.

Are you blowing fuses or are the bulbs blowing? Blowing fuses would be a sign of any wires or metal contacts in your brake circuit grounding out or shorting on themselves. You'll have to check all of the wiring in your brake light/switch circuit to be sure.

you most likely have a short to ground somewhere that is causing your circuit to allow to much amperage to flow threw. any more information, what circuit is it in?
