hi, can anyone tell me where the relays are on the 95 Ford escort 1600 please? I've got a problem with fog light. When I press the button the button light doesnt go on but the fog light does. However, it doesnt stay on and goes out when I take my finger off the button. I've already changed the switch and that wasnt the problem.
There are main relays under the bonnet in front of the battery. The rest, including the fog light ones, are on the rear of the fuseboard, under the steering wheel. Remove the fuseboard cover, and six screws holding the lower fascia cover. The fuseboard has a clip at the top; undo this, and the board hinges down, revealing the relays. (Note that the clip may well have a cable tie round it which you will need to cut. The clip sometimes comes undone, and the fuseboard rattles!)
You don't mention whether it's a front or rear foglight problem; front is R25 (White), rear is R19 (Grey). There is also a module for the front ones, R21 (White).
Many thanks indeed Chris. The problem is with the rear fog light - my escort doesnt have front ones. I'll dig out the relays on sunday when I have time. Have you any idea of the fault that I described in the OP? Im not niave with vehicle electrics but this fault is annoying - not to mention an MOT fail.
Confusingly, Haynes describes a rear foglight relay, yet there isn't one shown in the wiring diagram. The feed to the rear foglight goes from the switch to the relay board, but is jumpered back out again.
A further confusion is that there was a model change in '95; your car could be a pre- or post-95 MY. There are significant differences. For example, pre-95 rear foglight fuse is F8. Post-95, it's F1.
I've looked on Autodata, but that has no diagram for lighting.
Neither pre- or post-95 models seem to use a relay according to the diagrams available. It's going to be a case of poking around with a multi- meter I'm afraid.

I think it's time to stick it into an auto electrician. Thankfully there's one next door to my brothers workshop - I hope he'd due him a favour so I can get a discount! Thanks for everones help.
Indeed, but the wiring diagram shows that the feed from the switch goes to the light via connections to the relay board. These connections are shown jumpered. I suspect that it might be to accommodate some peculiarity of regulation in a non-UK market.
To eliminate the switch, use a suitable piece of wire to join together the Grey/Yellow and Grey wires if a pre-'95 car, or Violet/Yellow and Violet if post-'95. If the light then works, the fault is still the switch.
I'm sure you could. But since the fault is likely a soldered joint failing, it would be nice to just re-flow the lot. And it's near impossible to separate the two boards to allow this.
