    Just purchased my 04 dc, got it home and realized the door locks do not work. Its like the only thing I didnt check! Anywayz, when I hit the lock\unlock switch, I hear a relay clicking around the fuse box area but no movement at all with the locks. I would hope I didnt have 4 bad door lock actuators! Any common issues related to my concern? :confused:

    Pull the inside of the door off. Meter the solenoids to see if they get voltage. Check to see if anything is binding in the linkage. You should be able to move the rods by hand easily.

    The rods and linkages seem to be free, as all locks work fine manually using the key or the door lock indicator. I have not had a chance to pull a door panel yet to check voltage, I just figured it would be highly unlikely for ALL 4 of the actuators to be bad.

    True. Probably not the solenoids, i got ahead of myself on the troubleshooting list. Easy stuff first. Did you try to swap the relays? If the trouble moves, it's the relay.

    Anyone? I have not had time to research it, is there anything different on the 04 tacos door lock system? Is it module controlled?

    For anyone else who runs into this problem. My door lock problem was inside the fuse box inside the cab. It is called a body ecu. It is a small 4" x 4" compter chip that is apparently only available with a wire harness. Just a cool $2600.00. Pocket change for you guys. Anyway, I was on the phone with the toyota parts dept. trying to find the right fuse box and noticed there were two pins on the computer board that did not look right. They were spread terminals. Just applied a little pressure with my pliers and presto!!!!!:D
