Default Fog light install issues

I have a 2004 9-3 Linear and I recently installed a set of OEM lights, but I cannot get them to work. I bought used OEM lights (had to replace bulbs, which I tested), installed them in the grill and bought the OEM headlight switch with the fog light button. I had Saab of Greenwich (CT) try to marry the lights using Tech 2, but they could not get them to work. They said the car does recognize the lights are there, but nothing happens when I hit the fog light button (the icon on the dash does not light up either). Can anyone offer any suggestions as to how to test different parts of the system to isolate the problem and get the right part. I have a feeling the headlight switch is the issue although all other parts of the headlight cluster work perfectly fine. Is there any way to test the headlight cluster or the wiring of the lights beyond the actual lights in the grill?

I have the same car and installed fog lights too. If you have the switch (with BOTH rear and front fog light buttons) and have had your saab mech try marry it to your computer and it STILL doesn't work it sounds like the lights you bought are no good. If there was a problem with you computer there would likely be other indicators and malfunctions.
**If by chance you don't have the right selector switch, it's an easy buy, and then that's definitely your problem**

I have the headlight switch with both fog buttons, rear and front. I also tested the lights with a battery tender that I have to make sure they worked before I put them in and they worked fine with the battery tender, so maybe the problem is further up the line?

Is there a fuse? Do you have power at the fuse? Is the fuse OK? I assume the switch does not actually turn on the lights, but merely sends a signal to some computer or other which does the actual switching. If you could find where the wiring for the fog lights originates, you could check it at the computer as well.

Is there a relay for your front fogs ( check for one in the engine compartment fusebox ).

How would I be able to check for power at the fuse?

you must turn on the switch light and after the front fog light switch, then test the tension in the incoming wire fuse. incoming tension come from the switch light; but first, check if there are wires from the fog light switch to the BCM in the wiring harness. the BCM via fog light option must be activated by tech2.

Do you know where I can get a picture of fog light switch and the BCM?

Anyone know where the other end of the fog light wiring comes out in the engine bay and where it needs to be connected to the BCM?

You will need to
Have your dealer re-program the underhood electrical center to configure the new fog lamps.

The dealer tried and failed (they did say they've never done it before). I read something that lead me to believe that the fog light harness was not connected on the end that needs to hook into the car(I connected the other end to the lights). Does anyone know where this end of the harness is in the engine bay and what/where it needs to be connected to?

step by step..... first check terminal 3 in the switch light connector for a GN (green) wire 0,35mm2.
this wire send the signal to the BCM connector, terminal 28, for/or only the option front fog lamp.
in the wiring hardness for cheaper have not all the wires options.

see if you have this wire...

You must take out the turn switch light. not sure how to... for saab switches, maybe you must unclip two clips by the sides.

somebody with the -wis can help you.

Lighting switch removal.
1) Undo the 2 screws and remove the lower facia panel on the drivers side.
2) Reach up behind the facia, release the retaining clips and push the light switch from position.
3) Disconnect the wiring plug as the swich is withdrawn.
4) Refitting is a reversal of removal.

I already added a new light switch control with the fog light button, inside the passenger compartment, so I do not think that is the issue.

Does anyone know where the fog light harness is hooked up to in the engine bay?

Now I am thinking the fog light harness must be hooked into the car properly because otherwise the temp sensor would not work. Does anyone know what the thing marked "????" in the picture is and also the thing to the left of the "Hooked into BCM." The "????" looks like it should be plugged in somewhere - anyone know where or what it does? Same for the the to the left of "hooked into BCM," although I am not sure this looks like it should be plugged in.
