Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
If you move the handle on the driver side will the passenger side lock or unlock? If you hold the key in the driver side door lock cylinder will it global open or close meaning the windows will raise or lower?
OK can I have the last six digits of your VIN?
There is a door locking relay which is a 5 pin change over relay that controls both the locking and unlocking. The relay may be faulty or the fuse may be blown. Please check fuse #2 (10 amp) in the passenger side dash fuse box. Pop the cover off the side of the dash and make sure the fuse is not blown. Let me know.
OK do you have voltage to both sides of the fuse?
Your black lead of your.meter to ground and place the positive lead to the top exposed terminal of both sides of that fuse. We should read 12 volts.
OK no problem.
Yes we should have 12 volts on both legs of the fuse. If not the fuse is blown. It is a 10 amp read. The fuse box is numbered but it is hard to see. With the door all the way opened use a flashlight to see the numbers.
OK good. The relay may be bad. There are two small micro relays in that box. Remove the 5 pin relay to make sure the connections are clean. We cannot swap it out since the other relay is only a four pin. With the relay removed we should have power to two pins and ground on one pin. You can take the relay to your local parts store to see if they have one you can use for a test.
The relays should be right next to the fuse box. There should be two small black relays.
They should slide out of the socket but you may have to use a small tool to disengage the lock tab on the side.
Let me see if I can locate a diagram.
Yes that is correct.
This should help.
