X308 Fog light switch

[Sapphirevogue]

I've recently bought a '98 4.0 Sovereign. Everything seems to be ok apart from the front/back fog light switch on the dash. No LED & no fog lights (front or back).  I've checked the fuse and that's ok.  Anybody got a suggestion as to where to look next?

Hi,

 

Firstly, check the bulb and fuses then you could look at the switch to see if there is a battery voltage reading present. 

If not, then you will need to check the wiring up to the switch.

If there is power at the switch, then check the wiring to the lamp (e.g. chaffing, break, etc).

Most importantly....make sure there is a good earth to the whole circuit as corrosion can occur between earth terminals and the bodywork (chassis earth).

 

Hope this helps to start the diagnosis...Good luck.

Hello Trevor & thank you.  I've had an auto electrician look at it and it would seem that some 'oik' had been playing with it between the MOT and when I bought it. Sorted now...a miscellaneous wire was found to be attached to the fused side of the power! Still not sure what that was supposed to do!  Anyway wire now removed and fogs & switch illuminations work ok.

Thanks again for your reply
