Update on my earlier post.

I got these new motors off amazon. They slot in fine once the actuator housing is open. Though, important, the shaft on the rear is 1mm too long. This prevents the motor from turning. I shaved the housing with a craft knife and presto, it works.

Door actuator sticky, motor ok - with video

Hi,

I have been having central locking issues on 3/4 doors on my wagon (2005 Legacy Sport). Threads on this forum (eg https://bit.ly/2RHh4g7) suggested the motors often get greased up and give out. I've taken a closer look at the back passenger door and the motor seems ok, but the mechanism seems to get stuck.

With the actuator plugged in to the electrics, I use the driver's door central locking switch. I flick switch to 'unlock' and the motor moves a little, flick again and it moves a little, flick again and it finally moves it's whole range. This is in the video: https://bit.ly/34oHbgR. I suppose either the motor lacks the power, or the mechanism has too much friction.

To test the the motor is functioning, I take the spindle thread off and put in back in the housing - the shaft spins just fine. I'm reluctant to tear apart the actuator any further to lube it as the mechanism has a stiff spring, and getting it back together with basic tools is possibly gonna be a pain. Also, it appears to have ample clean white grease.

Any advice at this point?

Strange how I have posted the solution to this problem and no one is following it.

 

You DO NOT need to replace the electric motor you need to clean it.

 

Stick it in a glass jar of petrol with a low Voltage DC supply attached to it and it self cleans itself.The problem is the oil on the motor brushes and armature.

 

Change the petrol a couple of times until it remains clear and then hit the motor with compressed air before running it outside of the submerged petrol and its fixed.

 

Did it with both my rear door locks two years ago and no problems since.

 

Petrol in liquid form is not flammable, petrol vapor when mixed with the appropriate proportion of air is extremely flammable. You keep the motor submerged in the petrol and run it. It actually pumps the fuel through itself if you try it.
