So my girlfriend has an 2008 xb and after we installed the fog lights the radio and a/c button lights don't light up anymore. Does anyone know what the problem could be. ?

My first guess would be a blown fuse. Were they the oem fogs or aftermarket?

Try the dimmer switch on the left of the steering column. I accidentally turned it down once and spent an hour looking for a blown fuse.

Good point - I always forget that's there. Wouldn't all of the dash lights have gone out though?

Oh yeah. They all would.

Also, make sure your main headlamps are on for those to light up. The gauges light up whenever the car is on. The radio buttons and HVAC buttons only light up when the headlamps are lit, as does a little green indicator around the gauges (location depends on which gauge pod). On an 08, it is on a gauge face itself.

(Sounds dumb, but many don't realize when what lights up, esp. at 4 in the afternoon on someone else's ride. So, just a suggestion/reminder.)

If it doesn't light when the green light and headlamps are on, then check the dimmer, then fuses. Also, make sure the dimmer was reinstalled/plugged back in when installing the fog switch on the side (where the OEM switch is, anyways)-> is easier to forget than you'd think).

The dimmer doesn't change the lights and yes the lights Are on. I checked the fuses and they all are good. I'm guessing its the dimmer switch. I'm not sure how to check it though.

Sounds like a blown fuse.

You didn't say if the fogs were oem or aftermarket. Did you install them yourself or have them installed? I assume the fogs are working properly.

I asked oem vs. aftermarket because oem is plug and play so it is less likely that something got messed up more than just a plug like TartanJack suggested. If aftermarket, maybe someone tapped or cut a wire under the dash for power and accidentally cut the circuit.

You said the fuses were good. Did you just do a visual inspection in place or pull them and check for continuity? Sometimes a bad fuse can be hard to see.

If you paid someone to install your fogs, take the car back for them to look at.

Did the fogs my self and hooked up my voltmeter and checked them too and they all worked as well. Fogs are aftermarket but they are exactly the same as the oem ones. I used the existing wiring for the fogs but used an aftermarket switch. I'm starting to think its the dimmer because it doesn't dim the gauges or anything.

Was this resolved?

Was this issue ever resolved? Mine is having the same problem after an add a circuit for interior lighting.
