Battery drainage

You'll have an easy job because there are no silly, unnecessary computers to draw current for their memory circuits.

First look for an aftermarket radio that is wired incorrectly, and a broken switch button for the glove box light. Unplug the cigarette lighter. If the heater sticks on, there is a thermal cutout built into the back of it that will switch on and off about once per minute.

If nothing is found there, remove the negative battery cable and connect a test light between the cable and battery post. If it lights up or glows dimly, remove the fuses one at a time until the light goes off. That fuse will tell you which circuit to look in.
