1989 Turbo II

Car was fine when my dad got it, but after going over a bump the headlights came up stuck on main beam, and it stayed that way.

This is what I've traced:

1 - Everything is fine with ignition off
2 - Turn on ignition and you can't turn main beam off.
3 - remove the ILLUM and/or TURN 15A fuses and the headlights work fine.

So I think the switches are fine so the problem might be in the fuse box or the loom.

 

well i had a similar problem on a yota rav 4... i just found a blown fuse and it fixed it.. strange.

check and make sure none of the harness is rubbing direct contact with something up front too...

 

yeh I've had a go at the harness - when I stripped the section across the front some water came out which is not good. I soaked it in WD40 and dried it off but no joy.

Now that I know that the sidelight/turn signal fuse is relevant I'll know what bits of the loom to focus on...

Cheers,
