Today plan to replace the interior bulb to LED, the fuse blown off. Resulted all the interior lights & driver main window switches not able to function. Has anyone encounter this problem? I believe is short circuit issue, probably poor earthing?

sounds like you have blown a fuse, replace it and all will be well

If it keeps blowing then maybe a faulty LED Former Mod/Member, with the most post & Chicken George Arch nemesis

I blew the fuse whilst changing the led in the roof, easily done if poking the old bulb out with a screwdriver. I forget which fuse no. it was . there are three fuse boxes in the car , under bonnet, under glove box and under the boot floor. the tool to extract fuses is in the under bonnet fuse box. At work

Take it back to the dealer, but beware if you have hard spliced into any wires or mucked about, cos they will say you have invalidated the warranty.

Rear fuse box for individual door locking.

Front passenger footwell fuse box for dash lock/unlock, fuel cap open etc and door ajar sensor/info and interior lighting.

Most of the legends are actually on the box and in the handbook.

Power problems are quite simple. You have a positive and a negative. If one touches the other for whatever reason, blown fuse.
