heater panel lights

[YasE30]

Please help my heater light and the ashtray lights has suddenly gone off while driving strip all the car including middle console heater panel obc the lot but still cant find anything driving me nuts for two weeks now i dont know what else to check when i check the wires for feed there is two lives dont know why

There are two lives because the one that should be earthed, the brown/white, isn't earthed.
The earth path for this wire is through the rotary dimmer switch that is part of the main lighting switch, but if that had failed, the instrument cluster wouldn't be lit as well.

Tanhks for the reply, thats correct thats where the problem is i did what i could to try to diagnose it but no hope at all dont know what to do

If only the heater panel and ashtray lights are involved, and the bulbs are good, then there's a break in the brown/white wire between the affected lights and the main lighting switch, but before where it joins the brown/white from the instrument cluster.
Three of these brown/whites join together at the rectangular plug and socket (12 pins or so???) behind the glovebox area (top right) - two join at one pin on the plug, and a third goes to the socket side, so this would be a good place to start.
You can temporarily connect the brown/white to earth at any point as a test, to see if the relevant bulbs light.
