Interior light delay relay - Where to get one?

[AceOfHearts]

In my quest to finally get the little niggles on the car sorted (its only taken 10 years ) I would like to get the interior light working.

It works on and off the switch but not when the doors are opened. The door switches have been checked and cleaned, and are all ok. The time delay relay I can't hear clicking, and would like to replace as well, but the one I got was 4 pin and the original 5 pin, and does not work. Anyone able to source original type ones?

If you are not bothered about the time delay for operating the courtesy lights you can easily bypass the relay and just have the lights on when a door opens
and off when the doors are closed.

Those relays are a known problem area in that they can discharge the battery. Relay is the wrong term as they contain some simple electronics.

Think it's a Ford part, search this PH group, been discussed before or click here

Couple of recent threads on PH here regarding the yellow relay.

My interior light was not working at all and the tall yellow relay was missing from the fuse board (top RH corner).

I got a used one from ebay, 5 pin 85GG-13C718-AA and tested it to prove it was working then fitted it to the fuse board.

I have the same condition to you now Lewis.

Not a complete success yet still working on it but I now have an interior light that I can switch on just in case I need it.

The bertram-hill fix is a good idea which I may resort to.

Have I missed this point...if I have I apologise...One of the aspects of the system is that the ignition key negates the delay relay, as such you will only see the operation as you walk away from the car. AND that the door switches have a super glued piece of rubber on the door (that on later cars is a riveted on piece of plastic). A@

Or one gets in the car in the dark, the interior light comes on, start car, light goes out, drive off....Yes?

Great link thanks, I had a go at checking the relay board earlier and the 12v supplies are there, but I don't think the ground from the door switches is reaching the relay, as I couldn't detect anything on that pin. However I know the door switches work as it reacts correctly to the central locking.

Once I figure it out I might just link it out as above though and remove that risk of battery discharge

I used the original yellow relay base to provide the short circuit. ( after removing the components)

Convenient and keeps the terminals covered.
