I have a problem with my vb sl/e dash lights. When i got it it had a blow fuse so replaced that and it blew when i turned the parkers on. so pulled the dash apart went through the wires and couldn't find any burnt or rubbed through or bad connections. Next i took out the gauge cluster and bingo they worked, so then i pulled the cluster apart and found a few burnt tracks.
Next step was a replacement cluster which i fitted today and all was working again.....for a while ( 2 hours i was fiddling and putting the dash back together and it worked fine) then i started the car and put my foot on the door switch for the interior lights and the fuse blew again, grgggrrgrrrrrr.
I chucked in a 25 amp fuse and turned them on again this time it blew the fuse to the light switch

replaced that and it blew the dash lights again

.
So i have replaced the light switch and gauge cluster checked as much of the wiring to the dash/ lights as i could and still have no idea whats causing it.
Anyone got any ideas?
