On my 85GT I've never had the left turn signal indicator light work for me on the gauge pod. I tried changing out the bulb but that didn't work so I just lived with it. I recently upgraded my gauge cluster with a set of el-glo gauges and replaced the entire gauge pod figuring that would take care of the turn signal light problem as well. I did use all new bulbs when I replaced the gauge pod but I still don't have a left indicator light. What gives?

I would check the connector.....maybe a bad contact/broken wire.

On the instrument cluster, right hand, back side, the clear connector Pin 2 has the LH turn signal indicator wire (light blue). make sure that wire is working. It has the +12V when the light is supposed to light up. the other side of the light goes to the black wire Pin 11 on the same connector. If the other lights are working, the pin 11 black wire should be fine.

With the connector disconnected, you can turn the key to on (but not start) and turn your turn signal stalk to left. With a VOM set to at least 14 volts, connect one lead to chassis ground (pin 11) and one to the light blue (pin 2) and see if it switches from 12V to 0V as the turn signals turn on.
The other end of the wire should be at the connector below the steering column (the flat, black connector Pin H, also light blue).

Thanks Dave, that's the kind of information I was looking for to trouble shoot the problem.

when you change out the bulb,you need to check the front and rear turn signal bulbs.its either the wrong bulb or the bulb filamet burned out and is makeing a bridge across the other fillament (duel filament bulb).

I'll check/replace those as well 007. I'm also in the process of swapping out the entire headlight system and wiring harness to a gen II system. Figure I may as well replace all the light bulbs while I'm at it.

Dash bulb has direct ground.
See any front bulb diagram...

Front L Turn is working?

Yes?
Change socket on dash bulb.
check plugs and socket that dash plug into.

No?
Check all bulbs
check C210 pin H, lt blue wire. C210 plug at/near steering column turn signal switch plugs into.
If pin H is dead, get tools for steering wheel and lock plat.

Just finished up the harness and headlight swap. With a know good bulb in the front turn signal in the front bumper, it does not work and the rear light stays on solid bright. No blinkie.
On a positive note, both my headlight motors work now.

What happens when you put the hazards on? If all the lights flash as they should, then your problem is most likely in the steering column turn/hazard switch assembly.

i am having this same problem my left signal doesnt blink and stays lite. the right side is fine... i have a new stalk. i already checked the buld and socket and swithced them to make sure and the problem is not there... i believe its a ground issue at this point cause the right side works perfect like it should...
when i disconnect the connection from the flasher and place my leads there i only get 12v-0v on right side...and solid 12v on the left ...everything works fine with the hazards on.. i already turned the buld 180 and tried different bulbs and different sockets...

so where is the bad ground..????????

My left turn signal on my 86 GT does strange things in the morning.
I leave around 4:30am. The left turn signal will turn on but BARELY blink every now and then.
Then in the after noon it works perfectly.

I think it has something to do with the weather. Who knows? Maybe a weather sensative relay. LOL!

I have had a similar problem with the front left turn signal. The turn signal housing up front is loose from the body, if it gets pulled away from the body the turn signal does not blink normal, but very slowly. If I re-align the housing back to the body it speeds up.

There may be an excess of oil and grease in the column that interferes with the turn signal contacts. Not sure what can be done about that. I wiped it a little. Maybe some compressed air? Carb cleaner and other chemicals would probably do more harm than good by messing up the plastic.

I had an intermittent right turn signal indicator before trying to rebuild the column several months ago, then no right turn indicator, but now it works. I also took the socket out and replaced the bulb even though it looked to be ok. It wasn't working before I did that.

I' had the same problem, my left side directional lights would not flash. It turned out to be a poor contact on the rear light bulb socket. Make sure the small contact tab inside the socket is making contact with the bulb. I had the reset it so proper contact was made and direction started flashing!
