1984 FJ60 dash lights out (1 Viewer)

[KDAWG97m3]

hey group
iIam looking to fix my dash back lighting lights. i have zero lights..I checked fuses in the cabin, all seem ok. Before I start testing wires, I figured I would ask the experts on maybe where to start first, hoping you have a quick fix....appreciate everyone's help...

Replace the fuse even if it “looks” fine.
Either that or check it’s continuity with a VOM

Which fuse controls the dash lights, if its “guages” I replaced and actually cut off the car. I tested them with a light, but I understand where you are going. Thank you. Also we are talking about the fuse panel driver side closest to door. Right? Making sure I haven’t messed anything. Really appreciate your help.

Are you referring to the instrument backlights or the trouble indicator lights (charge etc)..

sorry for not clarifying. Instrument Back lights, Trouble indicators work.

Can you check if your front parkers and rear tail lights are active when your headlights are on?

There's a relay up under the steering column that controls all parkers, instrument backlights, and rear tail lights.

You should also check you havent got the dimmer switch wound all the way down.

My parking lights and tail lights work. I have played with the dimmer, hoping there was a short in the switch. Nothing.

Anything else?

You've twisted the dimmer switch/ knob in both directions? If you twist it all the way counter clock wise makes them go out. Try turning the knob clockwise a bit and see if you get lights back. Also, did you do something prior to not having dash lights?

Of course. Nope. Bought the truck this way.…

Think you need to test your dimmer/rehostat.

And pull the gauge cluster and see if all the bulbs are burnt out. Maybe the PO never drove at night?

Have you pulled the bulbs to check? My last truck had all of them just burnt out.

Just checking. I have seen folks on this forum go head over heels before checking simple stuff. Like Dave said, I'd look at that rheostat and start checking continuity and power/ ground there. I think it's pretty unlikely that EVERY bulb is burnt out, but who knows.

I've never seen a legible 60 series schematic (maybe one of you can post it) but I'd definitely do some multimeter work while looking at that.

It's not uncommon for that Dimmer (Rheostat) to get burnt if wires were shorted in that circuit. Remove it and test for continuity and resistance.

That dimmer is NLA but you can get it used.

Dimmer switch / Rheostat repair - cheap

When I bought my FJ60, it had a jumper in the connector that went to the dimmer switch, I removed it and plugged it into the switch so I could dim the dash lights again. Then my dimmer switch started failing, sometimes it would work for about 15 minutes, then the dash lights went dark. Lately...

The dimmer has failed. I bypassed mine years ago.

Any chance of good quality photos of your wiring diagrams from that manual? I havent seen decent ones yet.

 

[KDAWG97m3]

thanks guys. I have bought two dimmer switches to test with. I have pulled fuses and want to try that prior to digging deeper. Appreciate everyone’s help. Would love that diagram somehow. I can’t find anything on our cruisers like that. Thank you again

I'll see what I can do.

Trying to copy the FSM electrical diagrams is a real PITA, as the fold out pages are 32" wide. I found this one available:
