Mk3 cortina sidelight problems!

[1430MK1]

Hi,

Can anyone shed any light on this please?

Failed the mot on a number of things, one of which was the sidelights.

The offside front and rear sidelights are doing some odd things.

With the key in position 2 and the light switch on the column in position one (side light ON position) they don't work

With the key in position 2 and the lights switch on the column in position two (headlight ON position) they work

With the key in the off position and the indicator stalk in the indicating right position they work as a parking light.

Any thoughts??

Thanks in advance

Difficult to say, but a lot of strange problems come from bad earths..

Cheers guys,

It's an 74 facelift and the loom is pretty original. I'll have another play with the earths.

I've got the ones on the inner wing, is there any more I need to be looking for?

Thanks,

Gareth

Sounds like the earths should be okay if they work in all but position 1? Can you get a spare switch to swap out? Or maybe strip and clean the one you have. Sounds like a dodgy switch to me.
Edit: just one side isn't working? Mmmmm....

It was the switch in the end. Just the indicators to sort now!

If you have any other probs or questions then Mr bortaf is your man for Cortina woes, I believe.

Brill, I've got another question coming up...

Thanks again for your help!
