All bulbs are new LED ,everything works perfectly except the left turn. this car was worked on by some clowns in Kamloops before I got it so I suspect front wire harness, not sure they ever worked correctly  as car has been stored and only driven around a bit , don't think I ever actually used the turn signals as I was up North in the boonies.

What do you mean hazards on front markers?

This year of cars from factory had headlights and combination parking lamps/signal lamps. No hazard lights (4 way flashers?). With the headlights on, the parking lights do not stay on like later cars. 4 way flashers came as an option but I have no idea when that option became available. Some people have added a 4 way non factory flasher system using I assume something made in China.

Is what you have factory original without factory optional 4 way flashers? Follow the wiring diagram and see where you have power in the circuit to the bulb not working?

yes that's the really weird part as it has no hazard light switch, but when you go from park lights to headlights front markers blink hazard?, when left turn signal on , otherwise all is good? This is on my 65 SD, both front park lights blink just as if hazard switch was on?

So park lights are on ,when you switch to headlights park lights turn off this is normal, park lights on all good ,right turn works as it should blinks both back and front, now turn on left signal , nothing all park lights on still, now leave on left signal and pull for headlights , headlights come on ,both front park lights flash as if hazards were on?

I think it's a wrong wire because I believe there is a wire for hazards coming from the same plug?It's pushing me towards this -

They are all LED and are new, seem fine.but thanks I'm up for all suggestions as this is a weird one?

So when you Google this is says flasher relay, could be possible as this one is for LED, will check it tomorrow, this plugs into the fuse block, that would make sense I guess?

As I reread your post I still think that you have a short between the turn signal wire and the parking light wire in your left parking light. If the contacts are worn in the socket the wires may be touching together. I bought new sockets for my car (made in China) and the sockets were such poor quality the contacts in the socket would touch together when I installed the bulbs. I had to actually pull the wires back against the spring and then install the bulb. That way after the bulb was in I could release the wires and they wouldnt be twisted. I also bought a box of 6 volt bulbs from Amazon a while ago, also China, and the contacts on one bulb were incorrectly positioned.

If it was me, I would swap the led bulbs for standard 1157A bulbs and see what happens. I tried to install led bulbs in the same year Beaumont and had a hell of a time trying to get them to go in. Never could get them installed properly. Took them back for a refund...China!

 Agreed.

I had a similar problem and found that the pigtail in my turn signal socket twisted when the bulb was installed. DC grounding issues can cause some strange things to happen. Took a bit to figure it out and resolved it with a simple fix.

Installing LEDs in an older vehicle can cause trouble too due to near zero current draw.

Also says this on Google and it now does appear to be the flasher relay causing this issue-

How did you ever make out with this? Myself I don't think it'd be the flasher, as it seems to work properly when signalling Right.
