No power to left turn signal. (1 Viewer)

[feralyouth]

I’ve been having an intermittent issue where my left turn signal doesn’t work, then randomly it’ll work for a little. Right turn signal works, hazards work and dash indicator works for both signals, although the left blinks faster obviously.

Bulb is good and connections look good. Used a multimeter and I’m getting no power to the connection point.

I’m thinking it maybe a faulty indicator switch, what do yall think?

What turn signal "connection" point are you referring to? You haven't indicated front or rear.
A "fast" flashing condition indicates a higher current draw which could be corroded pins in the connector, bare wires etc.
There are two common failures that cause this. First is the trailer wiring harness/convertor box that has a high rate of failure. The second is leaks from the sliding windows dripping into area where the jack is stored is a connector that gets damaged.
A third possibility is the actual light socket failure of the ground.

Also, what year truck?

Have you installed any LED bulbs on any turn signals or anything else external?

I’m referring to the connection point after the socket to the car. I’ll take a look at the others then.

You could be having a problem with your combo switch, which controls turn signals and high beams. I'd think that if your hazards work then the rest of the circuit is pretty much proven. There's info on the part in this thread:

High beams will flash but won't stay on - anyone know how the switch works?

I'm trying to figure out why my high beams don't come on when I push the light control switch forward to the locked position. They work when I pull to flash. If this is TLDR, my actual question is at the bottom. I'm looking at the dimmer combo switch (84140), which is pressed and released...

No led in turn signals.

yeah that’s what I was thinking. I haven’t been able to locate any issue in the wiring. Thank you, I’ll check it out

If your hazards work properly then everything greyed out must be working. All that's left is the combo switch.

These are the three combo switch wires referenced in the wiring diagram above. I believe G is +12v, G-Y is RH signal, G-B is LH signal. For some reason my 94 has G-W instead of G-B. You should be able to activate your signals by shorting G to one of the other two terminals, as the switch should be doing. W-B is your ground, but if your bights work then you know it's good. R-W and R-Y on the right control the high beams. The lubricated black nub on the left gets flipped up and down by the turn signal stalk.

This is probably more answer than you needed but I recently spent a bunch of time figuring this thing out.
