fan and temp knob lights
 

of the 3 dials , only the middle one is illuminated. i did bang the dash and managed to get the temp light on but when i banged it again it went off and hasnt come on since. is this likely to be a loose wiring issue? if so, any ideas on solving it. thanks

My lights packed up awhile ago and looking into it I think it’s the bulbs which are a bit of a nightmare to replace so I’m staying dark. Maybe worth checking the fuse.
