Unable to open doors. Assistance welcome

Hi gang,

I’m new to the Disco Scene. Just purchased myself a 96 Discovery SD and I’m trying to get the doors open. It’s half taken apart at the moment, it’s a project I’m working on putting back together. My main issue is, the back doors and the rear door won’t open from either the inside or outside, even if I pull up on the lock from the top of the door. The passenger front door works and so does the driver’s door, albeit just from the inside since the outer handle is disconnected.

I don’t have a fob at the moment and there’s no power lock switch installed on the driver’s door. I’ve heard of a “super lock” issue but I’m not sure if that would apply here.

My question is, would anyone know how I can get the other doors open? Do I have to remove the interior door panels? Is there a relay I can jump to unlock the doors if that’s the problem?

Thanks

Hi. You'll have tor emove the driver's door panel first, at the latch actuator there should be an orange and a pink wire in the connector, disconnect it, use wires and apply +12V to the orange and ground to the pink wire in the plug toward the harness, this should activate all the other door latch motors to unlock but if the passenger door unlocks when you unlock the driver's door with the key means that this circuit is working so there is a wiring issue somewhere to the other door lock motors and in this case you'll have to apply voltage to each door motor's plug on the same colour wires and if they dont unlock this way means that the motors are fubar

With a 1996 D1 … I assume yours is the SD… all doors can be locked and unlocked mechanically via using the door top pins and also with the key on the front doors and rear tailgate normally… as the locks are mechanical your locks are seized maybe.

Pulling the 15amp fuse in position 5 on the upper aux fuse panel under the dash will isolate the central locking system, and there’s no super lock on D1 locks.

With the central locking, when locking, but the doors unlock means the master actuator is out of sync … the same in reverse unlock will lock.
