I suspect it's the clogged sunroof drains. I will fix those too but wanting to understand my options with the BCM.
Any help / suggestions appreciated.
Thanks,
As a side note, did you check the BCM area for any water leaks?

First and foremost, find the source of the leak and get that resolved. It makes no sense to do anything else at this point.
ASIDE FROM THE LIGHTING, ARE THERE ANY OTHER ISSUES WITH THE CAR?
That broken red wire is for connector M119, pin #11 at the BCM. This supplies 12V+ (constant/fused) to the BCM. I would suggest you clean everything up and repair that broken wire. From there, button everything back up and see if the problems are solved. I am willing to bet that if you took a jumper from that wire to the pin, your interior lights will work.
The BCM is a tough little module. It takes a lot to "break" it. It can happen, but is rare. If, after you complete the above, the issue persists, then you will have to look into replacing the module. To answer your question: yes, the BCM is specific to the car (coupe/sedan/'vert) and WILL REQUIRE PROGRAMMING for the iKey, security, TPMS, and some other functions. You are not here yet.
Yes, my plan is to fix the broken wire & see if my interior lights work.
I also plan on inspecting and blowing out the sunroof drains as well as check for other leaks around the cowl area.
I am hoping that I don't have to replace the BCM - Fingers X.
All the interior lights are working now - M119 that supplies 12v that was broken was the culprit.
Does any know what tool is required to remove these pins?
I am now going to investigate the leaks...
Any help / suggestions appreciated.
Thanks,
Don't even need to go in the engine bay. Take off A pillar trim, take off the side dash plastic trim and you have enough space to get your hands in there and put the coupler on.
oh, you do have to pull back the carpet to get access to the ac drain but it's like 4 clips.
Does this mod require anything other than removing the cowl cover and battery, such as disassembly of the A-pillar, etc.?

This thread here has good pics and details on rerouting the sunroof drains. A few simple tools, some 3/8" ID tubing, a few fittings (I used brass (personal preference)), and a few hours is all you need. This mod should be on everyone's priority for a multitude of reasons...

Do not waste your money on the extraction tool. All you need is a small, metal "pick" to press the locking tab. I use a old jewelers screwdriver. Tomorrow, I will post pics for how to release the terminals from the connector. It is not hard, but can get VERY aggravating.

Here is the official publication from Nissan TechInfo on the different connectors and how to unlock the retainers and remove the pins/ terminals (using their ridiculously overpriced "extraction tools").
The M119 connector is a NS-16FW-CS (NS Family, 16-pin, Female terminal, White housing). The following shows how I remove the terminals/ pins using a small jewelers screwdriver. Any HARD METAL "pick" will suffice.
THIS PROCEDURE WILL ONLY WORK ON THE NS FAMILY OF CONNECTORS. DO NOT TRY THE SAME PROCEDURE ON DIFFERENT CONNECTOR TYPES. YOU WILL F*** IT UP!
IMPORTANT! Note the orientation of the terminal as you remove it to ensure you are inserting it correctly upon reassembly. You should feel a solid "click" as the terminal gets locked into place. Any resistance,STOP! and check orientation. This is not one of those "if it don't fit, force it" moments. Your partner might be forgiving, these terminals/ pins are not.
Patience is key and with the limited space to work, it will get frustrating, fast. The good news is this connector is the easiest to de-pin.
As with any guide, you assume all risk for working on your own car.

Hi I am looking at my own BCM and am a bit confused on how you figure out what pins are what and what connector is what lol, I have the service manual pdf with me and it will mention connectors like R11 and numbered pins but without a visual im having a tough time trying to figure out which connector is what etc. How do you correlate the harness and pin names to the ones in the vehicle?
In the PG (Power & Ground) section of the FSM there is a "chapter" entitled "HARNESS LAYOUT." This will show all of the connectors on the individual harnesses. R11 is Roof Harness/ Connector #11. Some years have the connector visuals within each section/ others just in PG.
