Headlight switch issue (1 Viewer)

[hollowbase]

I've got a 75 FJ40 that has less than brilliant headlights. After replacing the headlights and not seeing any improvement I proceeded to check for wiring and connection issues. I discovered there was a voltage drop of a little over 2 volts coming out of the switch. I cleaned all the connections from the fuse block forward and shot some contact cleaner into the switch a few times. Now I'm down a little over a volt. Has anybody ever disassembled the headlight switch, cleaned it properly and reassembled it? Used switches are really spendy and are prone to the same problem mine has. If it can't be disassembled what are my options?

I followed this site to clean and redo my wiper switch. I believe the headlight switch is similar.

I just finished reading some of your posts where a guy had basically the same wiring issues I have. The plug was discarded and replaced with 5 individual wires, all red. Thankfully, they were numbered on both ends. Do you sell the connectors for both ends? Is rehabbing the switch viable?

Maybe a " USED " switch from EBAY is indeed a BAD idea ?



Perhaps a Professionally Restored one that comes with a NEW OEM PARTS Service Spec connector is a better idea .............

I looked at that, you would think the processes would be similar. Worth a try, thanks for the info.

What are your prices on the restored one with the connector and do you have a connector for the other end? Mine was removed.

My instrument cluster lamp isn't working, also the one that makes the heater box control light up. I see there is a resistor in the switch, and I see it on the wiring diagram, suggesting that the resistor is bad. What do I do?

Not a resister ..

It’s a potentiometer…

That’s for the twist rotate interior illumination feature you will never use ….

You should start by simply updating all your old beat down and burned out Fred Flintstone filiment bulbs to the latest 2022 LED DIODE technology…

LED …

MAX Lumens type

Then you will be very happy you can see what is what at night time ..

I would have never tried twisting that knob, lol. You fixed it, sort-of, contacts might be dirty and it is kinda fickle? Really nervous as three of four vehicles have mice dining on dried hackberry seeds right now. I'm holding off on the LED upgrade for aesthetic, color-temp. and brightness considerations.

I have a late 71 light switch. I opened up the clamp tabs cleaned all the internal parts and regreased. It worked great after, its possible.
