I have a 2004 Sonata 98,000+. Recently both of my foglights have stopped functioning. The indicator on the dashboard shows that I have them activated by the switch on the lever on the left of the steering column (same switch to turn on headlights) - but neither of them work.

NOTE: About 1.5 months ago, my transmission pressure line burst and spewed fluid all over the lower front of the engine compartment. After the repair, (by on-sight mechanic), I used CRC Brakekleen to dissolve and dry up residual transmission fluid. Not long after is when I noticed they weren't working.

Could it be related????

I tried replacing the fuse - nothing. I find it hard to believe that they are both burned out simultaneously.

Could there be another electrical problem that wouldn't blow the fuse but still kill the lights?

 

Check the bulbs first.
