Hello everyone, I'm new here and I'm having trouble trying to figure out what's wrong with my 2012 Pilot. The issue started a couple weeks ago when the driver side rear power window stopped working. Wouldn't move at all, when pushing/pulling the switch for that window, the switch on the rear door makes a clicking noise but nothing else happens. I wasn't too concerned at the time, my 3 year old sits there in his car seat 99% of the time, and I dont like him putting the window down anyways. And then about a week later the power door lock on that same door stopped working, it will not lock or unlock with the remote or with the master switch on the drivers door. A few days after that, the lift gate will no longer unlock either with the remote or the master switch on the drivers door. (And yes, I have tried the switch on the passengers door as well)

I took the door panel of the drivers door, and did not see any signs of water damage or wear and tear on the wiring. I took the master switch out the drivers door to check for any broken connections in the board, and everything seems fine there. I'm wondering now if it could be a problem with the multiplex control unit. But I cant seem find any reliable information as to where this is located on the 2012 pilot. I suspect it attached to the main fuse box under the dash. But I'm a little hesitant about tearing that out without knowing for sure that the control unit is there.

Anyone have any ideas or advice to help me out in this situation?

Greatly appreciated!

 

Every electrical issue has to be investigated with the multimeter by checking whether you get power and ground where required. Are you reading +12V and 0 Ohm to the ground at the door lock actuator and window motor?
