Hi Carkiller Team, I have a 2010 Honda CR-V EX-L AWD with ~192k miles. It has an issue where the front passenger and back hatch doors will not unlock. The car has a FOB and physical key. The car and FOB batteries were tested and are fine.
My ask is for a sanity check on my path forward or if there’s more I should test or consider. Here’s the details.
Attempts to unlock the front passenger door was made four ways: a) using the FOB (trying while both outside and inside the car), b) pressing the power unlock button on the driver door panel c) from outside the car manually using the physical car key in the front passenger door lock, and d) from inside the car manually attempting to toggle the small unlock switch on the front passenger door near the door opening lever. Also, for d), the unlock switch would not physically move to the unlock position (stuck in lock).
There is no back hatch door external manual key lock or internal manual hand lever/switch to unlock, so no unlock attempts could be made.
The other three doors (front and rear driver, rear passenger) work as expected under all lock/unlock situations.
Online research mainly suggests a) front passenger door latch/lock actuator, b) wiring short. I’ve decently inspected the electrical wiring coming out from the car body and into the front passenger door and all appears fine (no frayed wires, insulation cracks, other visual abnormalities).
Online comments discussing simultaneous front passenger and back hatch door locking issues (as is my case) state the front passenger actuator serves as an electrical “relay” (for lack of better term) to the back hatch door.
If anyone has more comments or ideas, I’m all ears. Otherwise, I’m moving forward with front passenger door actuator.
Thanks for all the good car advise you share.
the unlock switch would not physically move to the unlock position (stuck in lock).
you should check the linkage rods inside the door.
back hatch doors will not unlock
often it's broken wires or corrosion from water ingress.
In all cases you want to measure voltage at each lock to see if the signal is reaching it.
@imperator thanks for prompt response. I’ll check it out.
Friend, I have owned a half dozen CRV's over the years mostly 1st generations but they have all had actuator issues window regulators and almost all have had wiring harness issues in the drivers side door and fender harness which causes widows and doors not to work.. Hopefully yours will just be actuator but if gets where your fob doesn't work at all you know its the harness...
@thdesha thanks for the input. Here’s hoping it an actuator issue and not wiring. Much appreciated.
