It would not hurt. Just disconnect the battery and wait 10-15min. before disconnecting anything else. When you unplug the connectors look for signs or water, dirt, corrosion, etc. In the meantime you can investigate for any water intrusion (check floor pan, cabin filter, etc.).
If that does not work, I would suggest you have a qualified mechanic look at it before you blindly start replacing parts. Any competent mechanic (not necessarily the stealership)- preferably one with the Nissan CONSULT3 software- can fully and properly diagnose the issue.
You guys got my blinkers and wipers to work again. Thank you!!
so upon further inspecting the BCM I found water and ice on it. I unplugged the battery and unhooked the BCM, then I put a heater fan in it for about 2 days. Plugged everything back in today and everything works. Now I did feel dampness under the passenger rug and one of the drain tubes has condescension on it. I’ll do my research before I ask here though. Below are pics of the bcm and the tooth pick is pointing to where the ice was.
What’s up guys so I wanted to share an update and if anyone else has this problem they know how to fix it- I finally got around to actually fixing the water problem. Everyone was right and as suspected the sunroof passenger drain tube was clogged. I watched this video below and it was exactly what I needed.
I’ve never really worked on cars and this was about a 1 hour job for me- it’s simple, just time consuming. Below are pics before and after I cleaned the sunroof drain.
Just a quick thanks again to the guys that helped me diagnose this problem!
Before it was cleaned After it was cleaned Passenger side A panel removed as well as ac vent in order to access the tube.
Thanks for the update. I am glad you got the issue resolved. I would recommend that every once in a while check the floor to make sure it is nice and dry. Otherwise, job well done!
