Fog lights don't work

Obviously you need wiring diagrams or you can't
work on any vehicles electrical issues

How would someone answer your question ?

The switch you replaced was tested & failed or your
on a Wish & Hope - Push & Poke strategy !!!

yes,
you need a relay

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!

First of all, did the vehicle previously come with fog lamps? I'm assuming it didn't. Normally, each YM (Year/Model) Hyundai wiring harness is complete for every feature which might be included with certain trim specifications. However, you probably don't have the multi-function switch which has the 'Fog Lamp Switch' on it (Left Hand Turn & Parking/Headlamp Switches). However, the wiring for the fog lamps is probably there, you just need the multifunction switch which contains the fog lamp switch. The illustration attached shows where the wire harness plugs into the fog lamp bulb. This connector may be taped up in the wire harness out of the way (since I'm assuming the vehicle didn't originally come equipped with fog lamps).

I have not run into this problem before. Usually, people either purchase the vehicle equipped with fog lamps from the factory or they add aftermarket fog lamps to the vehicle after purchase. In your case, you are trying to connect factory lamps that were not there from the factory? I'm not sure that you will find the connectors you are looking for. I do know for certain that the factory fog lamps are computer-controlled and that if the vehicle was not equipped with them from the factory, then the computer will not be programmed to make them work. If the wiring and connectors are there at all, they will be coming from the Totally Integrated Power Module (TIPM) located on the left fender. The factory wires are WHITE/YELLOW for the left fog lamp and WHITE/ORANGE for the right fog lamp. What about control switches,wire, etc. Did you purchase all of that as well?

If your PU didn't come with factory installed fog lights then you will need to replace your headlight switch with a fog light enabled headlight switch.

Here is a link to the factory dealer-installed instructions.....

You only need to get the components you don't already have. The headlight switch that is fog enabled will pull out for fog light operation, if yous doesn't you need to replace the switch and do some wiring as shown in the pdf file linked above.

Hope this helps!

Should be a separate switch on dash for fog lamps. Depending on factory,dealer or after market installation switch can be anywhere on dash, console or overhead console.

Do not fit these lights yourself,you must take the vehicle to the dealer to have it done .Firstly as vehicle wasnt factory fitted you need the original homoglonation certificate from the manufacturer for the model with the foglights fitted,then you need a installation project drawn up by certifide auto engineer with the relevent technical qualifications (i have them) then they can only be fitted by a garage with an added value tax certificate,then vehicle must be presented to the local vehicle inspection depot to be mechanically inspected all over weither its due or not,the relevant paperwork plus the fee presented ,then a new vehicle registratrion document issued showing the changes.Failure to to this will cause the vehicle to fail its inspection when next presented as paperwork isnt correct ,the lights are ilrevelent as to weither they work or not,but if fitted from new they must work.Also if stopped by the guardis civil and paperwork checked,and they notice then you risk having the vehice impounded their and then on the spot ,big fine and the cost of the removal truck.

I bought the factory kit from Ebay. It came with clear instructions including the new headlight switch assembly that includes the fog light switch. I think it was under $150. Once installed, you have to see the dealer so they can program the computer to run the new lights.
