Okay, this one seems to have been done to death, but I've tried about everything I can think of. Here's the deal...

Every light in the car works fine, dome lights, glove box, dash, console, all front and rear, except the left front turn signal. It doesn't come on or flash when the signal or hazard is on.

The dash light flashes normally, and the rear lights work fine. Right side is perfect.

I started with the ground, seems okay. Replaced the socket assembly and checked the bulb and all fuses. Checked the turn signal switch...it's okay. Checked the connections at the firewall, and under the dash...seem okay... Replaced the dash harness...for other reasons, but had my fingers crossed.

Obviously I have to be missing something or it would work. Probably something simple...

I would first run a length of test wire from the socket ground to the battery negative post, just to make sure it has a good return path. I'm sure you have the correct bulb in place.

Next, I would turn on the hazard flasher and push in on the wires to the socket, just to make sure they are contacting the bulb. If no light, then remove the bulb and measure to ground the supplied voltage from the flasher.

If you have 12 volts, then follow the wire back to its next connection and check the crimp of the terminal to the wire. If there are some strands broken, replace the terminal and re-crimp. Keep following this pattern until the faulty crimp/broken wires/strands are found.

The meter is of a high resistance to show voltage, but, the light bulb filament is of low resistance to draw more current than a few strands can handle verses the complete bundle provided, hence the bulb doesn't work.

Had the same problem on mine. It was the connector that went thru at the inner fender up front. I had power at the dash, thru the firewall and all the way to the connector. Wired it direct without the connector and wala. Then found another connector to replace the bad one.

Wound up being a half a..ed splice in the harness behind the fender extension. One of the wires was holding on by a strand... Spliced on the rs underdash extension from the old dash harness. Same connection, and the wires weren't melted. Working like a champ now.

I'll put that forward light harness on my list of things to do next winter...

Thanks for the help fellas!
