HVAC lights INOP

Hi there...I have a 2002 Jetta GLS 2.0L automatic with a sunroof...all dash lights are working exept HVAC control lights. Is this bulb or could it be fuse?

The reason I suggest maybe fuse is because none of the HVAC lights are working. Are they all lit by the same bulb?

If it is bulb, could someone describe to me how to replace the bulb.

Any and all help is much appreciated.

there all lit by one bulb.

1) remove the center knob with a pliers (make sure its on 0 )
2) use a 1/4" vacuum hose and push it on the bulb and pull out
3) put new bulb in the hose a little and push in the socket and twist and pull out at the same time to get the bulb to stay
