The other day my for lights just stopped working. So i checked the 15amp fuse under the hood and it was blown, I replaced it and in between that and the time i turned the key on to make sure they worked it blew again. Is there more than one fuse for the fog lights? Any ideas on what could be going on? Its an 2001 silverado

 

See if Water in light my uncles fills up like a fish tank mine don't. See if plug is wet

 

Yeh, sounds like the bad relay. I would recommend you to replace the fog light relay before going any further if that doesnt work you have a short in the circuit.
BTW, the new fuse you are using is right size as old one? Coz most of the time this is very stupid thing we have missed.

The other posters offer great advice. You may consider checking page 6-75 through 6-79 of the owner's manual for additional assistance. I also recommend checking the relay.

I tried a new relay and it did the same thing. The fuse blows. The fog lights are H.I.D fog lights if that makes a difference? Like i said they were working fine and all of a sudden the one day they just stopped.

 

check the wires and unplug the the lights if it does not blow with the light unhook probable a bad blub

 

Okay ill give that a try because thats what i was thinking today at work also.
