I’ve had a latch assy on order from Rimmer Bros for a few months now (on back order) due to an intermittent RF Door Unlatched warning. Today it quit locking or unlocking with the fob, and the tailgate doesn’t open. I know I need a latch, but is there a temporary work around? I’ve ordered a FQJ103240 which should be correct for my VIN and LH drive. Maybe there’s a better source for this latch?
All suppliers are showing it as subject to suppliers stock, which would be Land Rover. Unfortunately LR themselves are showing it as out of stock (https://parts.jaguarlandroverclassic.com/fqj103240-latch-assembly-front-door.html). Tailgate locking is supplied by a ground from the RH front door latch so if that door is unlocked the tailgate is too. I don't see why you couldn't fit a RH RHD latch though.
Thanks Richard. I may need to give that a try.
RHD drivers side latch has 3 microswitches, as does the passenger side although only 2 of them are used, so you'll probably get one microswitch more than you need. You don't have a key lock on the RH side so the keyswitch won't be required.
To allow the tailgate to open, you need to ground the Green/Red wire from the RH front latch, either at the latch or at the connector behind the RH rear panel in the boot.
Thanks a lot Richard. I just took it all apart, cleaned it and put it together. It still doesn’t work with the fob, but I realized that with it manually unlocked, the tailgate works, so it should get me by until I can get a new latch mechanism.
I got my RHD RH Front door latch actuator and it does indeed fit, however the CDL actuator (motor) still doesn’t work. With the door manually unlocked my tailgate works. All the other doors work. I tried another door outstation from a parts car I had, but it’s the same.
I surmised that if I put power across pins 1&4 at the plug of the new actuator, the CDL motor would move, supposedly power one way to lock and the other way to unlock, but it doesn’t do anything when I do that. My understanding of how the motor works must be incorrect.
A broken wire in the bellows between the door and the body would be my next suspicion, but I tried manipulating that area and I would have suspected it to at least work intermittently when doing that.
Any other ideas?
Two latches both with a dead central locking motor would be one hell of a coincidence. Are you sure you are counting the pins correctly? Pins 1 and 4 would be the ones that connect to an Orange/Black and Pink/Black in the loom. As you say, power one way round should lock it and power the other way round should unlock it.
Yes, thanks Richard, orange/black and pink/black on the door loom side. I agree, two dead motors would be too much of a coincidence. I need to keep digging.
I've got a latch with a duff keyswitch here, I'll try bunging power onto the two wires in the morning and see what happens.
Thanks
