can you put a multimeter in the socket and see if its not getting power? maybe the leds just went out, oddly, at the same time?

 

I will try that, but that seems like an impossibility.

 

At least it's an easy test. Rule out the simple answers first!

 

People like to throw money and parts at their vehicles based on "feelings" and not hard facts or simple testing of components.

Its been said above twice already, test the plug. Most foglight systems have a fuse and a relay.

 

Another bulb could nn cited did not work either. It must be the relay.

 

Fuses are good?

 

I'm still looking for the fuse and relay location for the fog lights.

 

Again, there is typically one fuse and a relay. Start testing the bulb plugs, relay, fuse, foglight switch, lastly the BCM

 

You could directly apply 12v to each bulb and see if you get any output. Or buy some cheap replacement bulbs to confirm or deny it is the LED bulbs.

Beyond that, look at the covers for all your fuses and relays. My guess is they're both under the hood in one of the black boxes, but the fuse could be in the cab somewhere.
