defective actuator central locking, ZV for sliding door does not work

Hello, with my Voyager RG, BJ 2005, the central locking for the sliding door does not work. It only jerks up briefly, but does not lock. After the removal of the internal cladding and the removal of the complete locking mechanism, I found the causer. The actuator ruptures only briefly, at the voltage input I can measure approx. 12V. I then disassembled the part, it was all smooth and well greased. The drive motor turns with system of 12V with reduced power and can therefore On the engine is the following “Mabuchi FC-280PT-20150”. (Original Made in Vietnam) Where do I get the engine, maybe one has a tip? I would also take the actuator completely with the housing. I called Conrad, nix. At ebay they stand at Hauf (USA, Canada), but no shipping to Germany. The parts cost so about 3,00$ depending on the quantity, plus postage. http://www.ebay.com/…/110606792845#shId At Chrysler there is unfortunately no problem. r the complete lock, for only 200,00 Euro, without assembly. It would be great if one or one would sign up. Greetings Holger
