Lights question

[The jiffle king]

Hi, it's about 2 years since I posted in this section, but I have an issue with my lights which I cannot solve and I've searched the archives and don't have an answer.

Just taken my car for an MOT after months of it not being driven (I've been working abroad) and it's failed on the lights.

The indicators work fine, the side and main lights don't though and nor do the brake lights. The fog(switch on the right of the 3) do work though and I have no dashboard lights.

I am guessing a relay has gone, but cannot find Steve Heath's manual to find out which one. Any ideas if it is this, or could be something different?

Not keen to take the dash out and check the switches as the brakes lights don't work as well.

Any ideas where I should look? and things to test

Many Thanks

Just been through the Bible for you (happen to have it in front of me).

These are some possible fuses to do the stuff that you seem to have problems with (fuse counted from the left (near-side):

Side lights - first fuse / 5th fuse
Main lights - second to last fuse / fuse 17
Dashboard lights - 9 / 10 & 11 fuses
Brake lights - fuse 17 / 18 / 19

Obviously every fuse box is different.
Could the dashboard lights being out be due to the button under the steering wheel to the left being pressed?

Good luck.

Steve.

Have a look in the driver's footwell to see if the brake light switch has stuck or isn't making good contact with the brake pedal arm. It's a Ford part if you need a new one.

As none of the rear lights, side lights & headlights work. i would suspect that either the main feed wire to light switch has broken/fallen off. or the first stage (side light) switch has packed up.
From what i remember from mine,..... when you turn the side lights on, the sidelight switch then supplies power to the headlight switch (and to the dash lights).
Also i think the rear lights, high beam & low beam have separate fuses AND relays. so it would be quite a coincidence if they have all packed up at the same time

Does the headlight "flash" work. i think this is also supplied with power from the sidelight switch (even when they are switched off)

The rear fog light should only work when the main lights are on low beam only. (if you use high beam the rear fog is turned off)

do any other electrical items work/not work ?
Heater fan, fag lighter, electric mirrors, windows, interior light ???

i'm not good with sparky bits but could it be an earth ?

Thanks for all these replies, I'm going to check the switch by the brake pedal and also the relays and fuses (Thanks for the manual information)

It could easily be an earth and I'll be checking this out too

Thanks for all your help
