Chevrolet Lumina Forum : “how do you stop the automaitc door locks from locking when you put in drive?”

look in your owners manual, there may be a procedure in there. if not you can take it to a shop and they may be able to do it with a scan tool, i'm not sure if you can with a 94, but if you can't then you have to get a wiring diagram and figure out how to do it by unhooking some wires.

i believe you are going to have to cut some wires. because that is run by a module

the only way i heard of is cutting some wires and hope u get lucky. but its a stupid safety feature. great way to get locked out

I believe that there will be a little electonic mechanism in the door that is attached to the door latch and locks on each side and if you took of the door panels you could probably unplug it from the door latch on the inside.

Take off the passenger side kick panel in the footwell. Should be 4 screws/plastic fasteners. Under that, there should be a large-ish white module that
is plugged in, but also has a wire bundle coming out the back of it (I think it's got a green and purple wire in it). Unplug that secondary connector.

You'll still have power windows, power locks, and door/headlight/seatbelt chime, but the doors won't auto-lock when you put it in gear!

I did this to my 93 Lumina Euro.

i followed the wire in the manual from door lock switch to door chime and cut wire at the chime

You shouldn't have needed to cut anything, just unplug the connector.
