I agree, it is most likely the actuator.. A new one costs 250us here in Norway..

Craaazy.. Got a used one fromebay for 19.90 us.. It has not been tested, but the seller had no reason to believe it was'nt working.

Before installing it, is it possibleto unplug the old one in order to test the replacement one.?

Also, is it possible to measure if there is any signal sent to the actuator when tryingto lock/unlock.? Just to make sure that the problem is a faulty actuator.

thanks..
