Lose headlights completely when I push the stalk forward for high beams. Anyone else run into this issue at any point? Was there a fix? (besides replacing assembly)
 
Yes! I had a Kwik wire harness installed, and it did that. also, i blew fuses.
turns out, I had the High and Low mixed on the column. cleaned the contacts on the switch. and I grounded each headlight individually rather than thru a ground circuit. problem solved. (for me anyway...)
 
If I run my windshield wipers on high my headlights go out. In my case it's a short that only comes into play on high and it blows the fuse.

Never use high beams--problem solved. Ok, not a satisfying answer. :)

lol, I thought my 'cruiser was Quarky
 
Had same prblem with my '68. Replaced (floor mounted) dimmer switch and all was fine.
 
wondering if this issue was solved? I guess I should check the bulbs then go through the switch on the column. I have a new FJ, switch on the column blows the fuse instantly. I just bought this FJ this week, PO said this used to happen and may be caused by the windshield wiper terminal touching the housing. Have not checked this out yet.

Ezra, it would help us if you stated the month/year of your FJ40. For future reference, the term"FJ" usually refers to Toyota's FJ Cruiser (new) not the older FJ40.

On older FJ40's the dimmer switch could fail resulting in no lights when high beams were selected. Bad bulbs on both sides is also a possibility.
 
I keep calling it an "FJ" and being corrected, something i never do in person but for some reason on this forum I can not stop. "FJ40"

Its a June 1973 FJ40, restored about 4 years ago, rust free (so that generally help avoid some grounding issues).

My gut has said it is the switch since it first happened, my blinkers are also not working, not sure if that could be related, I was guessing that was a grounding issue at one of the signals. The PO used to have an issue with the wiper wires grounding to the casing, but I disconnected the wiper motor wires and still have the issue.

Is there a way to visually tell if the high beams are blown?

Thanks.

Not really, there are no tell tale signs of a blown element.

Quick way to test headlights: Get a piece of wire long enough to reach from the battery + to the headlight socket on both sides. Have someone hold one end on the + battery terminal while you insert the other end into the back of the headlight connector on the Red/Yellow (High Beam) wire then on the Red/Green (Low Beam) wire. You should get the bulb to light up in BOTH wires if both elements are good. If one works but not the other then that bulb should be replaced. DO NOT TOUCH THE WIRE TO THE WHITE/BLACK WIRE IN THE HEADLIGHT SOCKET!!! That will be a dead short and will create all kinds of drama... :D
 
sounds like a plan, I think I just need to start at the headlights and work my way back. Thanks for the advice.
