Turn signal issue.
79 f150.
Just two main issues. All bulbs and signals work, with the exception of the front left bulb when signals are engaged. I went and bought new bulbs and replaced that one that wasn't flashing. But it still is not working at all. So, I assume wiring is next. (a part # or direct link would be awesome)
On top of this, the indicator cab lights for turn signals don't come one either. I can get the left to blink inside if i hold the turn signal lever just slightly upward... then the light will start blinking in the cab. I can hear the clicking when they are initiated however.
2nd issue is that my signals don't auto cancel after making a turn. Is that normal for this trucks? I know my steering itself is jacked up.. loud.. hard to turn.. lots of drifting, etc.

On the surface, if I make several assumptions, your problems point to a faulty turn signal switch, but you need to answer all five questions first.

Need to look and notice that difference as I haven't with parking brake on. As a side note and something else I need to fix.. the E-brake doesn't work - cannot push it down. 'stuck'. feels like i'll snap something if I push harder.. anyways. next time.
the right cab never does, no. kinda a flicker.. i've seen before.. but rare. and hasn't flickered for a while now.
Thanks man! I'll check out the flashing on the outside when I hold the stick up to the point it almost clicks off spot. see if she flash'n.

If the front right signal works just fine, yet the right indicator does not (or is intermittent), check the bulb or cluster connection. The front right signal and the indicator light come from the exact same output of the switch - so if the front right signal works, the issue has to be local to the indicator bulb.
This could be an issue with the cancel cam in the switch itself.
