I really have no clue why my fog lights will not turn on. I have a 1989 Rx7 vert. I ordered some H3 HID fogs (I thought the stocl bulbs were burnt out). When I took my bumper off, took me a while , I took off the stock bulbs and they looked bran new! So I believe it can't be the bulbs. I checked out the fog fuse and it didn't look burnt out. I also checked the switch and relay and they looked ok to me. I'm really frustrated and I want my fogs to work! So please anyone, HELP ME OUT!

 

did you try to plug the new bulbs in? my fog light bulbs don't work, looked ok, but the multi meter shows an open circuit, so they are bad...

 

Yea I haven't tried that yet but I was thinking about making sure they work. I mean they are brand new but I will still try if they work

 

its a simple circuit.

there is a foglight switch, which is just on or off, which switches a relay, which never goes bad and that powers the bulbs.

the only trick to the whole thing is that the headlight relay powers the fog light relay, so the headlights need to be on for the fog lights to be powered.

the other trick is that the S5's that didn't come with fog lights, do not have the relay installed.

 

Wait so your're saying the fog light relay never goes bad?
