Hello all!
As per the odd topic title, I have recently purchased an RX400h, which I'm very happy with. Since it's an old car now ('07) it obviously needs some TLC, but i'm also happy to do that.. so I started with a few things, one of which is the rear doors were not locking when locking the car.
The doors would not lock with the key or through the driver's door button, but in both cases the car does try to lock them and you can see the locking buttons inside moving rapidly, but then ending up unlocked. So, i thought the issue here would be either the cables or the actuator itself.. so I bought 2x actuators to replace on both rear doors.
I did this today and upon initial testing (before fully assembling the door panel) things seemed fine - the car locked the rear door with the new actuator and then unlocked etc. Then I plugged in the window control button and it went straight back to the old behaviour where it just wouldn't lock. So.. i thought it might be connected to the other side's door not working properly and I went ahead and changed that actuator too. It initially started working... but then once I assembled everything back together it would lock the doors occasionally.. then it wouldn't and so on. It's quite random unfortunately. Then I got to a point where it would 100% lock all doors, but would not always unlock on of the rear doors and I thought fine - this is better than leaving it unlocked and thought I would call it a day until I find more information. Well all was well until I parked the car back in my garage space, which is quite steep. I left the car, used the key fob to lock and it just would not lock the rear doors again.
I tried searching the forums for similar issues, but did not find anything, so I apologise if this has been discussed already.
Any help on this would be highly appreciated!
