307 right front door lock motor

First of all hello to everyone my right front door when I opened the doors from the key, I went to a master that does not open from the outside, said the right front door lock motor should be replaced, I wanted to consult you before changing what happened before, thank you in advance for your comments.

I think I would suggest you disassemble the engine and clean it with a good contact spray.

I agree with my sonerkyl friend, the dust-dirt-mud lock mechanism does not function, or the iron wire attached to the outside handle on the lock inside the door may have come out. The interior trim of the door is a bit troublesome to disassemble, remove the inner mirror cover, the frame around the inside of the door opening lever, then you will remove the screws of the door interior trim by pulling up the inner trim from the pins, pull out the speaker cable, then open the dustproof coating bag from the place where it attaches with a brush, look inside the lock. But if you don't understand, I'd say stop by and get it easy
