U will need to pull the radio out of the dash and remove the top cover of the radio chassis, under that cover there is a tiny light bulb in a little socket that twists into the back of the dial display, the bulb looks like a miniature peanut, this is the back light for the radio display, u can buy the bulb at any full service parts store or at the dealer, about $1

you need to put gauges on it to see what its doing wouldn't be over charged unless some add to it with out knowing how much it had a low charge can make it cycle as well

Under the hood in the fuse and relay center. Check your owners manual, if you don't have one go here

maybe the ball joint or tie rod check it .

Yes I went nuts with the dead battery problem till I found TSB_EL015-03. Seems the frist half of the production year 2003 Tundra has a problem with the tow package relay being left energized if you leave the lights in the daytime running position so that they turn off by opening the door, it will run the battery down.Toyota knows this, won't do a recall, but there is a kit you can get that is listed in the Technical Service Bulletin EL015-3. When it tell you to use a special tool to remove a pin from the large connector (red) don't bother, you will never get it out. Just cut the red wire and use a crimp tool to splice it to the kit's wire. There is no room to work it, just cut it and splice it.http://www.toyotanation.com/forum/123-truck-archive/74107-2003-battery-draining.html
