in the fuse box
its in the fuse box mate
I can't remember, but the most common cause of failure is the switch on the tailgate, not the fuse.
On the fuse box cover there will be a daigram to show you the fuse layout. Normally its fuse location 15.
This recently happened to my 2004 vectra and it was the element in the lighter which cost £56 to have replaced at a garage
In the opel vectra it's on the side of the dash board passenger side. No. 2 - 7.5 A, and no. 23 - 30 A.
It's under the right hand side of the steering wheel.
check the wires and switch and maybe relay
the fuse board is to the right of the steering column, also there are a couple of others under the bonnet in and amongst a few relays.
On a 1998 18i 16v Artic it's fuse #22
if its a vectra b (95 -01) then its under the steering wheel there is a recess you put your hand in and pull it. on the cover you pulled off its stamped on there?
