This happened to me also. Did you put in the new relay under the dash? At first my light wouldn't come on either; until I went back and pushed down on the relay again.
Thank you. Your switch appears factory item. Does the switch light up with just the PARKING LIGHTS on? On the facebook group, someone told me that the switch does not light up unless it is at the "on" position.I just checked mine it is supposedly the correct one. (I bought it online from some store maybe on eBay with high ratings so I can't be 100% sure it is authentic). There is no square LED up top just the fog symbol. It does appear to light up but no difference with fog light ON nor OFF. The instrument cluster in front of the steering wheel has a fog light indicator that goes ON and OFF.
Thanks. So with the parking lights on, the fog light switch lights up. That means that there is a illumination wire that feeds the switch. You also stated that the lighted symbol does not change intensity regardless of being off or on so the switch does not give the status of the fog lights but via a dash light instead. Great, I will be using an aftermarket switch then.It lights up with the lock symbol (only) and the traction control. The USB does not. All three light up with the parking lights ON.
