Hello, the vehicle turn signal light supposed to blinked for some seconds when the driver's door is open (as if the hazard lights were on). The right side are working properly (passenger side) when the driver's door is opened, both the front and back but the left side is not functioning (driver's side) both the front and back. If the turn signal or hazard light is on from the switch it will respond.
What could be the fault?

Hi,

I need to better understand what is happening.

The left signal turns on if the driver's door is open, correct? Is that with the key off? Also, I'm not sure what you mean when you say if the hazard or signal is on, it will respond. Do you mean if the key is off and the signal switch is on, the lights flash when you open the door?

_________________________

I am going to attach the entire exterior lighting wiring schematic. I'm not sure if you are comfortable reading through them, but take a look and see if it helps. Also, let me know if I am correct with what I said. If so, I will try to see where there could be an issue.

I overlapped the pics so you can easily follow them

Let me know.

What I mean initially was that the hazard light (that triangle symbol in between the dashboard) is functioning if engaged so the problem is not the bulb.
The left signal turn does not turn on when the driver's door is opened but the right do.

Okay, then it is the left side regardless of the door. I was getting confused.

If the left doesn't work (front or rear) there is a good chance it is the switch itself. What you need to do is check the power at the switch. The schematic below shows the wire I need you to check. According to the schematic, the wire out will either be red or white. (See pic 1)

See if you get power to it when the key is on and the left signal is selected.

Let me know.

Good morning, please could you help trace the flow of current for the number 3 diagram you sent earlier for without and with wireless door lock control?

Hi,

I attached four pics below. They show the entire exterior lighting system (wiring schematic). I had to cut the pics in half to make them more readable, but I did overlap them so you can follow them easier.

Let me know if this helps.

From the diagram, the parking light is it the same as the main head light?

Hi,

The headlamps aren't on that schematic, so I'm a bit confused.

I attached two pics below showing the headlamp schematics. Note that pic 1 is with DRL and pic 2 is without DRL.

Let me know if this helps.

Thank you very much both will be helpful but I want you to cut them so that I can see them clearly, they are some how blur. Sorry for the inconveniences.

Pics 1 and 2 are with DRL (daytime running lights).

Pics 3 and 4 are non-DRL.

Let me know if that helps.

Thank you, the light are now functioning properly. I was disconnecting the fuse one after the other, until I saw the exact fuse that control it. The fuse was okay anyway, I just cleaned the contact point and fixed it back, the fuse is a big fuse (among those fuses under the dashboard at the driver's side) unlike those ones in the fuse box, it's blue in color and it is connected with thick wire (red color). I would have shown it on the diagram but I couldn't find it, I don't know if it is part of Antitheft system.

If it is a heavy gauge wire, it sounds like it is a power supply to several fuses. Is everything working now?

Yes, everything is working now. I wished I knew where the fuse is coming from.

Hi,

Is it possible for you to upload a couple of pics of the fuse you are referring to? Hopefully, I will be able to identify it.

Let me know.
