vt headlights

[interceptor]

My wife's vt commodore has a problem with the headlights,when she turns them off by switch,they stay on,so she turns the switch to on,then off a few times,then they go off,and same the other way,when she turns them on,they dont go on,until she turns them in off position,then on position about 3 or 4 times....Is this a common problem with the vt model,and do you think its the switch which is crook???.........
Cheers.....

Could be the switch or a dodgey relay. Try swapping the relay with one of the others of the same size and number to test it.
