2005 Fog light problem

I've been reading countless threads on this subject since I discovered my oem factory installed fog lights do not come on in any position of the multi-function switch.

The relay is fine (traded it out for others and even bought a new one).

The fuse is fine (traded it out for others).

Not sure if there is a high beam relay which may be stuck in the on position or not. I looked but can't find one.

Bulbs look fine (took both out to examine them).

I'm stuck wondering if it's my multifunction switch. I get no fog light indication in the instrument cluster when I pull it out, so...maybe. Not sure if this is a telltale sign or not.

Any advice on what I should do before I put down the money for a new multi-function switch?

I found a cheap aftermarket one on ebay and amazon (standard motor products cbs-1208 combination switch) for $40 shipped, but not sure of quality.

What would be my next step to make sure I try everything before changing out the switch? Thank you all very much!

Re: 2005 Fog light problem

Just to make sure you know how the switch works, you pull out (like towards the door) on the end of the stalk when the lamp postion is in anything EXCEPT off. If its in automatic they will only come on with the headlamps.

I like to verify the circuit past the FCM, if you remove the relay, then use a jumper wire from the battery (preferably with a fuse in it) to pin 87 (there should be a diagram on the side of the relay that will show you pin 87). If the fog lamps turn on your golden with that portion of the circuit.

Ultimately, with no fog lamp indication on the cluster it would be an indication someone isnt getting the message to turn on, either its not being provided or its being lost somewhere.

Im not sure if I have an some kind of media issue on my personal computer right now because my wiring resources are not functional right now. Hopefully your issue is just operator error (how the switch works, I know my wife couldnt figure it out).... if not Ill continue trying to figure out the problem with my computer and get some further diagnostic suggestions for you, probably tomorrow evening (I currently have a hell-of-a headache tonight).

Yes, I have been pulling the switch toward the door. Tried every combination. Everything seems fine. I can try the jumper wire. But dumb question...is a jumper wire something I go buy...or use a wire I may have around?

I know...

Re: 2005 Fog light problem

A jumper wire is just a short length of wire used to bypass and complete a circuit. You probably have something suitable at you're house if your like me.

Using a jumper wire, I got the fog lights to come on. So...am I still premature in guessing it's the multifunction switch? All the other switches on the lever work, so I know the lever is getting power. I guess it COULD be something in the run from the switch to the fuse box, but not sure how to track that down.

Re: 2005 Fog light problem

Re: 2005 Fog light problem

I have the same issue. I have jumper pin 87 and lights do work.
Did the switch fix the issue?
