Anybody know why my fog lights on a mkV R32 won't


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!

I HAVE PAYED $20 TO GET SOME HELP WITH MY DASH LIGHTS NOT WORKING. ALSO MY PARKING LIGHTS WON;T COME ON. ALSO MY FOG LIGHTS WON;T COME ON. I HAVE ASK YOU SEVERAL TIMES TO HELP ME. IT MAKES ME THINK. YOU...


Sorry about that, I must have missed your post or something. The park lights and the panel lights are usually on the same fuse and therefore on the same switch. The fog lamps are on a separate fuse and switch/circuit, although the is nothing to prevent either of the fuses going at the same time. Look at the fuses first, if they are blown replace them, but if they blow again some more investigation will be required. The parking lamps/panel lights are unlikely to have a relay, but the fog lights may.

The fuse must be in the main fuse box. The position and function of the fuses is normally marked on the inside of the fuse box cover and also in the owner's handbook. If you don't come right with these, work your way through the fuses looking for a blown one. To ease your search the fuses you are looking for should be around 15 to 20 amps.

My 2002 Lexus GS300 fog lights will not turn on. Where is the fuse for the fog lights? Here-to-for, I've changed individual fog lights but neither operate now. Please help. Mike


The fuse for the fog lights could be in the Fuse Convenience Center under the dash or in the Engine Compartment. It is most likely a fuse, relay, or could be the Fog Light Switch. You need to test each one starting with the Fog Light Switch first,

Dodge dakota selector switch and relay switch


A selector switch is what you use to turn on or off a circuit such as the lights or wipers. A relay switch is used by a circuit that has a large current draw and a relay uses a small source of current to control a large usage of current. Most fog lights use a relay to control the fog lights. You turn the fog light switch on (that is a selector switch) and the current from that circuit then activates a relay switch to let the larger current draw that the fog lights use go to the fog lights and you have light. A relay also controls if the fog lights are on when the bright lights are on. (on most cars if you turn the bright headlights on the fog lights will go out until you go back to the regular lights)

Hope that helps.
Good Luck

Fog lights will not turn on in my 2008 rdx


When the light are turned on, the dim lights have to be on the up position on the lever that turns the light on. I had my lever in the down position, which is for the bright lights and when pushed up will automatically put on the dim lights and fog lights when turned on. I should have realized this problem my-self.
