Hi all,
Just bought my first Grand, its a 96 LTD. Got as a list of isues to sort, one of which is the door locks. I can unlock all the doors and boot with the remote or the key but can only lock the the drivers door, all the other doors have to be locked manualy. Now the actuators are clearly working as it will unlock, I have found a few posts about the issue arrising from the chime unit. I have removed most of the lower dash and found the said unit, quite unlike the ones described but it is where the chime comes from, and cleaned all the contacts and checked all the solder joints, also all the instruction I have seen state that the relays are in the glove box, mine are in the passanger foot well. I have had the door pannel off and cleaned all the connections with no luck. I belive there are two relays, one to lock and one to unlock but my car came without a handbook so if anyone has a diagram of the relay/fuse layout it would be very helpfull.
