Heater control lights

[bench]

Hey everyone. Im having trouble with my heater control lights not working sometimes. Ive checked the connections on the back and seem ok. I dont have A/C. I can go out in the car, stop off and leave the car locked up, come back and the lights not work for a couple of days and then they will work again for a while. Can anyone help?
Thanks, Bench

its "common" for the bulb to go, but from the sounds of it you've got a lose connection somewhere or maybe the bulb is faulty.

i'd try replacing the bulb first as they are only a few pence and pretty easy to change.
