Hi I need help with a problem my IX35 just started with. The fog lights will only come on with high beam. It seems there is a loose connection on the control stick. Any thoughts on how to fix this?

It would be easier to find clues to the fault using a circuit diagram.

There are slight differences how the fog lights are wired and generally are intended to be used only with dipped headlights but for exact operational details the vehicle handbook should be consulted.
You didn't mention what the rear lights including the rear fog lights are doing?

The fog lights usually derive the supply or the control for the circuit from the main lighting circuit so it would seem the fault is before the point in the lighting circuit of that connection.

one wire will for high beam
one wire will be for low beam
the last wire will be ground wire
as fog light have only one beam you can use the low beam wire and parallel wire it to the fog lights
that way you have the head lights still and the fog lights as accessories correctly wired according to regulations
how to do it simply-- find the low beam power wire ( light switch on low beam and power at the light bulb check ed with a multi meter set on volts
solder , piggy back, or double plug in a connection into that wire and run one wire to the left fog light and one to the right fog light connect each fog light to an individual ground wire and connect those wires back to the ground wire for the main lights
Now having done that simple addition to the lighting system another problem has come up
The wiring will now be too light to carry fog light current and or the light switch will burn out
To over come this problem, the circuit needs a relay
fit a relay on the bike and now run the low beam wire to a terminal of the relay
run the other terminal wire to ground
this enables the relay to operate when the low beam is switched on but at this will not switch on the lights yet
now you have to run a heavy gauge wire (fused at the battery) to one of the power terminals of the relay and from the other power terminal to the connection for the fog and low beam lights
Now it all works switch on the high beam and no for lights
change to low beam and the fog lights come on as well
All nice and legal
Of course if you don't care about being legal just buy a 30 amp toggle switch and run a fused wire directly to the switch from the battery to the lights and then to ground from the lights
You will know that the generator / alternator for the bike will not be able to run the fog lights with or without the main lights so what will you have achieved

fog lights have to be wire in correctly to be compliant with the high way code of regulations for lights

they should be wired through an independent switch, through a relay connected to the high beams relay so that when high beam is selected they are turned off

The law prohibits the use of fog lights in any condition except fog so to use them as extra lights is illegal and costs a big fine

I suspect it is the headlight switch

Check the relay that powers the high beam, if memory serves me the relay is shared between those two circuits.You can swap the relay with a known good relay to prove if that is the issue.

You can not have High Beams on and FOG LIGHTS at the same time. The Body Control Module controls this. You may have a bad Body control Module

hi,
you could just run a possitive wire from the back of your high beams straight to your fog lights then earth the fog lights stright to the car. this will work just make shure you disconnect your battery before playing with the wire's. if your not sure what you are doing i would recommend you take it to an authurised electrican. as for the high and low, same system but i would say it probably would over load the fuse creating more work for you.

FROM: Lusty Kid:

Your fog lights should not work with high beam... they should work with the low beams. they are connected wrong, which probably drew too much current through the light switch burning out the contact points for the parking lights in the switch

Start by Fixing the fog light connections to work with low beams. Appears to me this was not factory installed. Aftermarket kit maybe! Then see if your parking lights work. If parking lights don't work still and everything else works, replace the light switch $50 at the dealer. The switch works the fog lamps when you pull out the knob to turn on the fog lamps when the lights are turned on. When the fogs are on you will see a little amber light to let you know your fogs are on. When you switch to high beam the fog lamps go off. Again if its not working that way, then is wired wrong. Needless to say, there should be connectors in the harness of the lights for the fog lamps. Use those if possible with the kit that you can get at the dealer, or you can splice the connector with those blue splicing clips sold at the auto part store. Make sure ground is ground when splicing and water proof the connection sith silicone and tape.

The fog light switch is located to the right of the rear wiper switch. Also the fog lights will not operate when the high beams are on. If the rear fog is the defrost switch,you are in the right area.If the switch is not there,they could have been dealer installed and are wired to come on when the low beams are on. Hope this helps,Good luck
