I've got a b4 passat wagon and for some reason the lights for the ac/heater knobs don't work, along with the ashtray light, and half of the radio lcd backlight :... I've checked all the fuses and not one of them seems to be blown I guess it could be the bulbs, but what are the chances of all of those being out at the same time? I guess its possible but I was just wondering if anyone has had this same issue and if they were able to fix it.
Yes, only one bulb for all the HVAC knobs; light is being distributed by bars similar to the one above - except round.
Pop the bezel around the knobs and you will see what I am talking about.
Bulb is in a holder attached to the back of the the center knob.
