Hi guys,
My fog lights went out one after the other in a gap of 1 month. bulbs and fuse look fine.
Whn I start fog lights they glow for a second then again off, I supect the relay.
Does any one know where is this relay located in car? I checked the ECU box (under the hood near driver side wiper, It doesnt have the relay for fogs)

 

Don't bother, its more than likely your headlight switch than anything else.
To remove it push the **** inwards turn it to the right until it stops, then pull it straight back towards you and it should come out.
Pull the electrical connector off and see if any of the terminals look burnt, if not try shaking the headlight switch, if you hear a rattling noise the switch went bye bye.
