Question about Toyota Tundra
Im guessing you are saying only the door switch fails on one door?
so it's THAT switch bad ,it's wires or its logic box is bad. (or mis programmed)
you never said what door, driver? ONLY? or ?
the other doors on many cars have parent locks.
so if other than driver, door, check those masters.
do you have the FSM. and working from its diagnostic pages?

SOURCE: Door locks don't work
Disassemble the paneling on left side ,under the steering wheel. Remove all screws and pull out the panel until you can you can reach behind it to remove the two Black Relays, on the side closest to Steering wheel. Remove the Relay covers, Clean the contacts with a 1/8 fine strip of 600 wet/dry sand paper. Only place the paper between the contacts, and pull out while holding slight pressure on the relay Armature. Turn over the sandpaper and repeat once again. Very gently press the TOP resting contact pad closer to the armature, to lessen the gap between the contact points, so the armature doesn't have to travel as far to reach the closed contact position. Repeat the above with the other2nd Relay. Replace the covers, reinstall the relays And test the Door locks prior to buttoning up the paneling. Note, a pair of long needle nosed pliers will help in removing the relays. Just Grip the relay and rock in Forward and Backward as you apply upward pressure.
