What specifically is your method of locking ? ie. (assuming car shut down now ) 1 ) sitting in drv's seat, doors closed ( how many doors UNLOCKED ?) you push electric door-lock button ? 2 ) sitting in drv's seat, doors closed ( how many doors UNLOCKED ? ) you push drv's MANUAL LEVER ? you push other door's MANUAL LEVER ? 3) your standing outside , drv's door is open , you push electric door-lock button ? 4 ) your standing outside , drv's door is open , you push drv's MANUAL LEVER ? you push other door's MANUAL LEVER ? 5 ) while doing #3 OR #4 car unlocks ONLY AFTER you goto SHUT the damn door ????? .............
.............Then there's using a remote FOB ????? Ya , No ? Wacha do'in here?
If you have the door switch @ rocker panel that registers - " doors ARE completely closed shut" , and they are getting " sketchy " , they can create havoc with the locking system ( may have BCM or Body Control Module notorious ).
Also you MAY try removing fuses ONE AT A TIME and note which one kills that ' bad action ' . You may pull fuses you THINK are related to problem ? But can be confusing that way . BEST , in this specific case, to SYSTEMATICALLY pull fuses row , by row , in interior fusebox ,replacing if not the " one ", if no 'avail' .....pull fuses in another fusebox like in engine cmpmt. Do those all SYSTEMATICALLY one by one , then replace & goto the next fuse IN-LINE on that row !!!
Good chance of figuring out what you want to know in your question ,ya ? Manual ONLY ?:chuckle:
p.s.IF ya find it ,What's the fuse designated for AND can you drive AND live with it out ?Till fixed?
