Interior lighting(dash and Gear shift are not coming on)

Remove the bulbs in question and verify they are not burned out. Verify wiring connections behind the dash are all plugged in tight. Inspect the "printed circuits" behind the guage faces are not cracked.

I would go with the corroded cables. You would have power to everything even with the alternator out of the truck.

the fues blow because there is to much hook up to it buy a 20a to replace a 10a and see if that works

It is likely the interior lighting dimmer control switch is defective or turned off.

Yes more then likely it is a fuse, don't forget to check the fues panel under dash as well as under hood!

check and make sure the brake lights come on when you apply brake. The shift interlock works off the same circuit so if the lights arent working it wont shift out of park. It is common for the switch to go bad.

fues, relay, fusible link, check interior fuse bloack

Fuses. Check those in the interior fuse box (left kick panel, below the dash--fuse chart on the cover) and those in the engine compartment fuse box (far upper left as you face the car). If, after you replace anything that has blown, it blows again, that would suggest a short somewhere in the system, or a bad light switch.
Hope this is of some help.

there a little switch on the shifter to stop it from going into gear with out the brake on .eather theres no power or switch is bad. it under the dash at the shifter .good luck

first of all check out the alternator and drive belt and if you have a keypad on the drivers door check it out for shorts
