Fog lights dont work

Fog light bulbs were both burned out. Replaced with new bulbs and still dont work. Small light on the fog switch does not come on when you push the switch to the on position. Any help to fix this would be great. The car is a 1988 Iroc Z. THANKS JIM

Turn on headlights, then flip switch.

I forgot to mention that I turned the headlights on first then flipped the fog light switch. Fog lights still dont work. JIM

Fog lights working now. Forgot that the headlights have to be on low beam for the fog lights to work. Check that Richball member. THANKS JIM

Re: Fog lights dont work

Re: Fog lights dont work

If my memory serves me correctly it's on the driver's side fender next to where the evap canister is. Should be right by the horn.

Found it... swapped in another relay, no dice. I will have to check to see if that relay is even getting power. For the '87, is there a separate fuse in the panel for the fog lamps?

Re: Fog lights dont work

Here is a photo of the visible link. It does not appears distorted in any way. I have not measured the voltage before the link (didn't see an easy open area to the lead), but measuring where the link ends in the socket yields nothing. This is the lead that is always "hot" correct?

Re: Fog lights dont work

you cant tell if its good by looking at it you have to use a meter. and the wire that is connected is all brown and melted, you can tell it has taken alot of current at some point. you have to make sure the pin doesnt look damaged and the area were the insulation is melted off isnt permanently damaged

Re: Fog lights dont work

figure out my problem. after checking all my grounding points, wiring, I decided to take a look at the switch. I removed the switch panel and discovered that I forgot to plug in the swith when I previously removed the gauge panel.

Re: Fog lights dont work

Hello I was hoping you could help me out I am not sure how to navigate this site yet. I replaced the switch and the bulbs and still no lights. When I turn them on it blows a fuse any ideas why is would happen? Also when I get on the gas peddle in gear when I get to higher RPMS it seems to cut power but not when in park. Any help would be awesome
