Help with Right Blinker not working... (1 Viewer)

Follow @FJ40Savvy advice and in the order he suggests.

I still think it’s a ground issue…but 1st verify that your bulbs are good!

If they are good, start with getting good grounds.

Both of these tasks are easy to accomplish.

How can a ground issue at the fender prevent the panel bulb from illuminating, when it has a separate ground (which is common to all other items on the instrument panel)

I think there are a number of issues. I'm betting the instrument panel blub is bad and there is a ground issue on the fender. Which is why I suggested to check the blubs first.

Here is the issue I found with the High Beam light in my gauge cluster.

Builds - Louie - 1973 FJ40 - A OEM work in Progress

Little Repairs - High Beam indicator was not working. I pulled to the dash to try and troubleshoot the problem. The blub was loose in the housing. It looks like the PO did a repair using a piece of plastic to have spring tension because the black plastic piece on the wire was black and...

Yea my high beam indicator was also dim - it now has a blue LED.
Switching the hazards on will certainly narrow it down.

Oops, accidental post. Not used to looking at the forum on my phone.

I think many are trying to say “start with the easy stuff before assuming it’s something more complicated”. Check the bulbs. Just taking a bulb out and putting it back made my turn signal indicator in dash start working again a couple weeks ago.

Yes, I believe there is more than one issue here. Be methodical, complete one issue at a time. Try to follow @FJ40Savvy procedure in post 19.

Any idea what bulb size is correct for the dash blinker light? Does the light housing just pop out of the dash to replace the bulb?

Based on your description, this is my assumption of instrument cluster currently in your vehicle.

Clusters, Gauges, Speedo & Odo meters

There seems to be a lot of questions about Clusters, Gauges, Speedo and Odo meters, so I thought why not set up a page as a reference guide / database / knowledge center? Over time I collected a lot of pictures. I created a Gallery with all the photos I have, which you can see here...

The blub housings come off the back of the cluster with a push and turn. The blubs are T53.

You could also replace these with LED version to make the indicator brighter.

Before you pull the instrument panel out though... do the hazard warning lights all work, and is the rear right working?

Be wary if you're testing the lighting circuits with the "continuity" function on your meter - some meters will buzz continuity through a cold bulb filament of a few ohms, giving the illusion of a ground when actually no ground is there.
Always use your low ohms range to be sure.

I hate commenting when I feel I can’t add anything of value, but having been exactly where you are, I’ll add my $0.02.

I’d start with new bulbs in the dash and at the turn signal. Then, grounds. Then hazard switch.

I had the same issue, but even my hazard switch resulted in solid lights all the way around. Ultimately, I re-wired my entire rig and threw in all new bulbs, and new combo lights for the rear and new turn signals in the front. Probably not necessary for you, but I had other (melty) issues.
