Fog lamps on 2004 Tahoe won't come on.

Fog Lamp relay and 15 amp fuse replaced. Indicator light below Fog Lamp switch on dash comes on which should indicate the lights are on. Marker lights and tail lights do come on when switch for fog lamps is pushed as is normal when headlights are off.

You need to check the bulbs.These are known to go out a lot.Also you can check that you have power to the lights with a test light.Sounds like a bulb or wiring problem.I have had a few of these that are broken off because they are so close to the ground.Depending on if your four wheeling or in snow country.Hope this helps.Good luck.

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!

My fog lights won't turn on Nissan sentra GEX 2002


There are several things that can cause your fog lamps to not work. The fog lamp circuits need to be diagnosed. Your entire fog lamp circuit can be tested at the plug for the fog lamp relay located n the relay box.

PIN 5 on the relay should have battery power at all times. This power comes from Fuse #43 (15 Amp) in the fuse and fusible link box in the engine compartment. If there is power at this pin, the fuse and the circuit between the fuse and the relay is good.

PIN 3 on the relay goes to the fog lamp bulbs. There should be continuity to ground through the bulbs on this pin. If you have continuity to ground, connecting a jumper wire between PIN 5 and PIN 3 should make the fog lamps come on unless there is a short circuit to ground, which will cause Fuse #43 to blow. If there is no continuity to ground on this pin, the problem is either that BOTH fog lamp bulbs are burned out or there is a break in the wire between the relay and the bulbs.

PIN 1 Is the battery power for the primary coil in the relay. This power comes from the headlamp switch and power is only supposed to be present here when the headlamps are on and the dimmer switch is on LOW BEAM. If power is not present at this pin, the problem is a bad headlamp switch or an open circuit between the headlamp switch and the relay.

PIN 2 Is the control circuit for the primary relay coil. The control circuit should have continuity to ground when the fog lamp switch is set to the ON position. If there is no continuity to ground with the fog lamp switch on, the problem is a faulty fog lamp switch, an open between the relay and the fog lamp switch, or an open between the fog lamp switch and ground E37 (right front of engine compartment) and ground F7 (left rear of engine compartment) Please note: This circuit has redundant grounds....if one ground is not making good contact, the other ground can still make the circuit work.

PIN 4 on the relay is not used.

If all of the circuits/pins are working as described above, replace the relay.

That is pretty much it... That is all you really need to know to get your fog lamp circuits diagnosed. Let me know if you need further assistance.

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 fog lights are not working, the relay is fine but not sure where the fuse is? Don't want to buy a service manual for this one simple thing. It does not tell you in the manual.


I have a 2004 f150 xlt triton. I couldn't figure out the how to turn on the fog lamps and the manual was not helpful.

Solution: turn the light switch all the way to the right and pull the switch (out) towards you. Push switch in and it turns off. The manual says to turn switch all the way to right but doesn't say to pull switch out.

Fog lamps dont work i check fuses and relay the switch shows the fog lamps are on


If you have not replaced the headlamp with HID, the next thing, are the high beams on ?

If you turn the high beams on, the indicator lamp on the main headlamp switch should go out.

Next thing would be to check the fog lamp relay in the fuse panel ( passenger side kick panel by the fuel inertia switch ).

The fog lamp relay is a half size ISO relay, you should be able to swap with the trailer tow parking lamp relay ( R201 ), to test with.

The fuse you checked is the F17, the fog lamp fuse for Relay R202, correct ?

How to factory wire fog lights on a 2000 ford f150. pig tail, relay, and fuse are there. Only no wiring from fuse box.


This is a common problem on 97-00 MY trucks, regardless of the trim level ( XL, XLT, Lariat ).

If you install the fog lamp fuse in the BJB ( aka Battery Junction Box, Engine Compartment fuse panel ) Fuse # 9 ( 15 A fuse ) and jumper the normally open contacts in the fog lamp relay socket ( see diagram below ) the fog lamps should illuminate ( to confirm what you have doing on ).
8491ddd.jpg
The problem usually is the main headlamp switch to the BJB is not in place ( this is the yellow wire from the main headlamp switch connector to the relay socket pin #1 ).
One easy route is to make an aux lighting relay & harness, or purchase one online. With this, you can cut the factory ends and attach them to the harness you purchased. There is an air inlet next to where the steering wheel column runs through the firewall. This would give you an easy route to the fog lamp switch. The fog lamp switch, you can buy the factory one, and change the yellow wire from the connector to your added relay, or just add a switch for this function.
This will give you an idea of what the DIY relay and harness would look like.
