2006 Getz
 

I have no central locking, radio or interior light.
This started after I disconnected the radio and saw a spark.
Checked all fuses under dash and bonnet all appear ok.

Have seen this before
Does the engine start?
Do the head lights turn on?
Check or recheck all the fuses under the dash.
There is a common fuse that all three use.
Also, does the central locking work when the engine is running??

I will check if door central locking works with engine on when daughter gets home from work. Other than radio, central locking and interior light everything else is fine.
