Fog lamps not functioning

[03yukXL]

Hey all,

I replaced the destroyed fog lights in my 03 Yukon. They still do not function. Fuses are good, swapped in a known good relay. led indicator comes on the dash when the fog light button is pressed. Is there a common fix for this? I have read a couple of common complaints but never saw an answer…

Thanks all

Didn’t you check voltage at the bulb? Did you replace with LED bulbs by chance? If so, flip them 180 degrees.

^^^x2^^^ Let's start by confirming that you have 12 volts at the bulb sockets when the fog lamps are turned on.

The bulb sockets also overheat and can be replaced with a new pigtail; you'll probably see the brown plastic when you have access to the bulbs.

Full disclosure, both new lights were bad from the factory. Kept the housing and replaced the bulbs with LEDs. All functioning now. Careful what you get on amazon…

Out of curiosity, where did you get the replacement bulbs?
