Hi everybody, so long from last time mading something on my fit...

Few days ago i noticed fog lights stop working at all both at the same time. I have an dlaa fog light kit installed by myself and after a few month i modified installation and ad a HID xenon kit, worked perfectly for about an year and a half, maybe two, but suddenly stopped working.

What i tried?:

Fuses, everything is ok.
Relays, all of them working.
Xenon kit, all the spare pieces working, even bulbs lights up when trying them directly to the battery (everything assembled of course).
Conections/cables looks ok.
Switches working good too.

Cant find the problem, the only thing i can see after so much testing is that when i try to turn on fog lights with just one of them assembled (probably with both will be the same) is that the 12v of the battery goes down to about 1.5v (when i unplug both kits voltaje keeps about 12v), supposed that was the battery, but its ok, and it keep doing it with the alternator working, why could be the reason of the voltaje going down? probably solving that problem will be enough to made them work again.

Thank you very much!!!

 

Solved!!! was the fog lights switch!!

 

Good to hear you easily figured it out. Wire connection on terminals and switch are most common cause due to vibration.

 

Yep! It was the first thing i checked, but as i was able to hear the relay working as i press the switch i understood it was working, it seems that it does but just for a few miliseconds so the relay close and open in the same click! Luckly it was that! Thank you!!
