If you only checked the fuses, then the next step is to check the bulbs themselves. There is a DIY thread illustrating the process to getting to them.

Now if the bulbs are bad, then it could be a relay issue (ones in concern would be the ones dealing with the high beams as the fogs go off when the high beams are engaged).

Do you have stock bulbs in those fog housings? Many folks (like myself) have upgraded to HIDs.

I have to ask, did you scroll the headlamp stock to the off position for the fogs?

lmfao .... trust me I have flicked the fog switch on 100 times and still nothing .... and the bulbs are brand new .... it got to be a fuse or something .... It happend when I tried to connect these after market lights into the fogs to test them out .... see below.

Shouldnt be... when I upgraded mine to hids it was a simple plug and play. I am wondering if u maybe fried the relay? Have you got a power tester to see if power is still running to the connection point?

^If you checked the CORRECT fuses, then a relay would be my next bet.

Have you checked the bulbs themselves to make sure you didn't blow them both somehow?

Did you check the fuse under the hood? I believe there are multiple fuses to check and I would bet money that a blown fuse is your issue. Unlikely that both bulbs went at the same time.

When I put in HID fog lights, one of the ballasts went bad and would blow fuses the second I installed them. I believe the fuse was under the hood.

Finally found it. You have to slide the side box out on the fuse box to get to them. See below.

Question... .can I put something higher than a 15 fuse? Say a 30? would that allow more current thru that wire to power HID fogs ... ect ?
