Headlights wont turn off?

2010 triton headlights stuck on lowbeam, highbeam not working only turn off when key turned off,also indicators and wiper functions not working. i removed the headlight/indicator stalk from column and lights still stay on,would this fault be a bcm issue? cheers

well with a 300$ flashlight you could go look for water intrusion.
id get a full scan at supercheap with the bosch and see if any codes could hint at the problem if not then it be a failed relay or something that dont sets codes.

Intrade's idea of a stuck relay sounds good. Also check earths to ensure there are no weird feedback problems. Indicators/wipers sounds like you should check fuses first.

Blown diodes in the ETACS ? If it is the fault & repaired the behavior could be changed with the MUT device that Mitsubishi use to suite .Maybe it was programmed for the European market.They have odd head light functions with headlights ,some with key out lights function some don't.But looks like you have a fault some where. Re the other no/go,s check relays op for wiper and indicators.Also clean check the plug at the combo swtich before condemning it.Also check fuses for wiper and indys as well .probably best to take it to a dealership.If it has blown diodes the wiper and indy circuit might be out too for that reason ,fryed.
