Well, First, you get the "dttech DIY auto repair person of the week award
" for at least LOOKING
in the Owner's Manual first! That is better than MOST Fixya users would do. Probably 90% of the Owner's Manuals in peoples glove boxes are still in the wrappers they came in from the factory!
The reason the Owner's Manual is no help in finding the fog lamp fuse is because the fog lamps do not have their own fuse. The power for the fog lamps is actually supplied by the Vehicle Electrical System Control Module (VESCM), which is located under the left side of the dash.
The fog lamp indicators in the instrument cluster are actually a completely different circuit than the fog lamps themselves. The Instrument Cluster Control Module (ICCM) turns these lamps on when the VESCM sends a message over the data communication line to tell the ICCM that it has turned the fog lamps on. So my guess is that there is no indicator on the dash because the VESCM is not commanding the fog lamps to turn on.
The possible reasons for this could be that the VESCM is not recognizing that you are WANTING the fog lamps on (due to a switch malfunction or a wiring problem between the switch and the VESCM) or the VESCM is malfunctioning, or the VESCM has detected a short circuit in the fog lamp circuits and is refusing to turn them on in an effort to protect the vehicle from burning to the ground.
So, in short, the BEST
way to figure out why your fog lamps are not working is to scan your onboard computer network for possible fault codes and check the live input data from the light switch to see if the VESCM is recieving the message that you are trying to turn the fog lamps on, as well as see if the VESCM is commanding the fog lamps on (probably not, or the dash indicators would be on).
Welcome to the world of modern auto repair where the vehicle manufacturers go to GREAT LENGTHS
to keep you from figuring out these thing for yourself an FORCE
you back into their dealerships for repairs......A whole other subject that really eats my craw!
