We have a 2004 pick up....I believe it is possessed....it either randomly locks the doors or as soon as the truck starts they automatically lock....what fuse or fuses (I see there are many) can I pull to turn off the door locks....I'm tired of having to either call a lock smith or break into when it does this craziness...TIA

 

Could it have an alarm in it????
Some aftermarket alarms, can be made to lock the doors, when the engine is started.

 

How long have you owned the truck; how long has this been happening? I know some rides are programmed to lock doors when you put the car in gear; our 05 Suburban had settings where we could change how the door locks worked.
