I posted this for someone else's car but I have similar car now so it works. There is a screw under fan speed knob, you need to unscrew it so that panel can move. Then you have to open bottom glove compartment and undo cables attached to fan speed knob/heater knob/air direction knob. Now this whole panel is ready to be pulled off. The bulbs can be replaced now.
If you dont want to do it yourself, get these bulbs separately from a shop. Ask any person who installs car sound systems to add those bulbs for you and pay him 100rs or so for labor.
