Guys

driver side left turn signal are not flashing but they are Solid - the rear left turn signals work - the dash flashes left
front passenger right turn are flashing and so are the rear

this is the bulb ?
the relay ?
fuse ?

I say the bulb - if so, is there another Trade number I can use that will work instead of 3157 (Natural Amber) -

I'm betting a bulb. You can get bulbs in amber and clear.

Canadian models have different signal light requirements...

I am not following your post one bit. Does the left side front and rear light up and also the dash when selecting a left turn from the turn signal handle??? I think youare basically saying they front and rear light but do not flash. Is this the situation??

Sounds like just the front isn't flashing ,but the dash indicates it is? Incorrect bulb?

Do the parking or headlights have to be on for this to happen?
Do you have daytime running lights in Canada?

Tom .... Basically

The left front lamps 3157(NA) won't flash when I turn left they just stay solid - everything else on the car lights and signals works fine

the dash flashs like it should just no lights flashing in the front left - the back yes

The headlights can be on or off it doesn't matter and it does have daytime running lights if I push the head lights button half way

I think the reason we are confused is this: In our cars, in America, there are two filaments in the bulb, the parking light filament, and the flasher/brake filament. I don't have a schematic in front of me, but IIRC, the turn flasher filaments are in parallel; front with the rear. The front and rear turn signals cannot act independently. If this was an American car, the only way the front can be solid with the rear flashing, is you have the parking/headlamps on, and you are seeing that filament lit, and the flasher filament is burned out. To further confuse the issue, I believe when one flasher filament burns out, the circuit doesn't draw enough current to heat the flasher plug and the remaining bulb (and the dash indicator) would also light solid, but I digress...

Short answer, for us Americans, the only answer in that situation would be, replace the bulb. If Canadian wiring is different, then I don't know

Easy way to tell, just swap the bulb from the other side and see if the problem switches sides.

Pull out the turn signal lever connector and focus on light green wire with white stripe. That's for front left turn signal lamp. Check this wire with your multimeter in ohm reading. You can compare it with White wire with light blue stripe. That's for front right lamp. They both should have almost the same reading. If they don't, trace that wire and try to find a problem. These wires goes in the loom on the drivers side of engine bay and have a grey connector next to the battery tray (closer to the firewall).

So basically he had a bad secondary filament in the 3157. Or another words on the high side filament on the signal side of the lamp. Basically he was checking it with his dims on and they stayed normal as the 3157 is a duel filament lamp. Explaining this issue was beyond me when he posted it. naturally the high side of the LAMP was OUT!!! have a great day guys

Well, checking bulbs should be mandatory before posting such a question. I guess everyone expected the check has been done, that's the reason why we are asking much more delicate questions and looking for possible (non present) issue. :(
