Toyota Repair: 1996 Land Cruiser High Beams, high beams, conductive grease


Question
QUESTION: I have the above vehicle and the latching high beams no longer work.  Momentary works fine.  I pulled the wheel and removed the handle that controls the hi/lo beams.  At the end of the handle is a ball bearing and a bent piece of metal and a push switch.  The push switch activates the momentary hi beams.  When you pull the handle towards the driver, that is supposed to activate the latching hi beams.  I removed the ball bearing and the piece of metal that covers the bearing.  I throughouly cleaned both, put some conductive grease back on, saw no eveidence of wear/pitting, etc.  Reinstalled and latching hi beams still do not work.  Everything is in new condition, no loose connections.  What else should I look for or am I missing a fuse or relay somewhere?  Thanks for your help.

ANSWER: I strongly suspect that the switch is still the problem because whether using it in the flash mode or the high beam mode the same circuit is used, so if it was a relay or fuse then both settings would be affected.

QUESTION: OK, I'm completely confused.  I replaced the switch with a new one, replaced the headlight relay under the hood, checked every single fuse on the vehicle, verified all connections were good that I could get to, and I still have no high beams.  Absolutely no change to my original problem.  I have worked on industrial control panels in the past, problems similar to this were always relays, switches, or connections.  Short of completely tracing the wiring, are there any other things I may have missed or you suggest I check?  Thanks.

Answer
In your original post you didn't say the switch was replaced, you mentioned cleaning the ball bearing and the metal plate, these are not the electrical contacts, the plate and the bearing simply keep the switch in position, so please clear this up for me, is the headlight switch new?
