Some lights are not working

Hi,

It is really hard to hear what you are saying on the video. However, have you done anything with the switch itself? IS it all exterior lights that are not working?

The body control module has a lot to do with the lighting. I attached the entire wiring schematic for the headlamp system. Take a look through them to see if anything helps. Also, let me know exactly what is happening. I'm sorry I couldn't hear what you were saying in the video.

I had to break down the pics to make them readable. I did overlap them so you could follow them.

No problem with the English. LOL Don't worry. By any chance, did enough water get in to reach the body control module? See pics 1 and 2. I did notice you had the dash taken apart.

Okay. If you have no power to those fuses, we need to back up. I need you to reconfirm power to all the fuses both in the passenger compartment and the under hood fuel box. Also, there are a few relays we need to check as well. Note that picture 1 deals with lighting and pic 2 the HTR fuses you indicated. Pic 3 is for the ecu and pics 4 and 5 are under hood power supplies. In addition to just checking the fuses, make sure there is power to them. Here are a few links you may find helpful:

The fuses you show in the above pic are in the vehicle and receive power from another fuses power supply, so a fuse may be bad before them.

Let me know what you find.

1) Okay, I am going to start with the high beam indicator in the vehicle. Does it turn on even though the lights don't? See pic 1.

2) Next, look at pic 2. It shows the power supply to the headlights high beam. Start there and lets work backwards to see where power is lost. I highlighted the power supply for high beam. Check those wires for power. If none, move on to step 3

3) Pic 3 shows power supply from fuses to high beam lighting. If you haven't already, check there. This is where I believe you don't have power either. I'm basing that on your video.

4) check blue wires to relay for power. See pic 4 If there is power, switch relays to see with others with the same part number to see if it changes things.

5) If there is still no power, follow the blue wires back to the body control module. See pic 5.
That is the body control module. Is there power there? Key on, high beam on. If there is no power there and the low bean work, I suspect the body control module is bad.

Let me know.

Can you explain what is meant by the interior light turns on with your test lamp? Are you connecting the lamp to power and then the wire?

You sound correct. If there is no power from the BCM, then I suspect the BCM has failed.

Let me know what you find.

Hi,

I hope you are well. First, I feel badly because i'm not 100% sure I understand what you are asking. As far as the blue wires, they supply power to the headlamp relays. Do me a favor. You indicated there was a clicking. Go to that relay and conform there is power out.

Let me know. Also, hang in there. I'll try my best to help.

Joe

Hi,

If the ECU isn't responding, it does sound bad.

I have a favor to ask. We like to keep the threads specific to one topic to help others. I hate asking, but could you start a new thread? I will watch for it.

Let me know.

Take care,
Joe

You are very welcome. If you have the chance, let me know if you get it fixed.

Take care,

Joe

Sounds good. I hope the other thread is going well and what I sent today was helpful.
