Fog Light's Not Turning on (Both of them)
 

Hi guys,

I have a 98 Durango with around 160k. Just about a year ago I replaced the bulbs for the fog lights and got them working again. Today I let my brother borrow my car, when I got it back, the fog light switch wouldn't turn the lights on. The switch's green light that turns on when you push it in, that light wasn't turning on. I'm not sure if there's maybe something I'm doing wrong, I checked the high beams (they don't work with high beams on) and that wasn't it.

Does anyone have any suggestions on this? My headlight casings are pretty bad, covered with film, so the fog lights are pretty important for night-driving.

Have you checked the bulbs again? Maybe they came loose for some reason. Or maybe they burnt out. Check the wiring harnesses as well.

+1 dan, i would check the bulbs, or at the very least to see if you have power at the plugs

Check for burnt fuses too

Check the bulbs again as advised and also wiggle it to make sure its seated properly, and if no go replace the relay with another one like it in the PDC. With the fog lights they're weird and the illumination light on the switch will turn on but the lights won't get power.

When on High Beams are on the fog lights are cut off, this is normal.

What I would do is swap the fog light relay and ensure that the low beams are on and see if they light up. If not see if the relay is clicking in the PDC, if not maybe a switch. If it is clicking then it sounds like a short from the PDC to the fogs.

Yea actually it's the opposite though, the illuminated little green light for the switch doesn't turn on, and neither do the fog lights.




Thank you everyone for the replies. When I get some free time I'm going to try and get this straightened out. My headlight cases are so damn dirty that the headlights on low-beam do barely anything. The only reason I haven't replaced them yet is because everywhere I look the new headlight casings can go for like $100 bucks each, even on ebay. Crazy.

have you tried to clean the headlights the cleaners out there work really well

When I had my fog light issue back when I bought my truck, it did exactly as you describe. The little green fog light wouldn't come on.

Replaced the headlight switch and they were good as new.

Concerting that the lil green light isn't coming on I would suggest you pull out the switch and test the switch.
