Mercedes Central Lying Problems 190

Only me Delts doors open. And the trunk, for this it has to be with the key each independent. The rear doors do not open as well as the bearing of reposting.

This wants to say that central lock does not work.
I would like to know the operation system and what I could do, because it gives me the impression that should not be difficult.
I have doubt that the system is pneumatic or electric

Thanks in advance

HI, FRIEND. Well a suggestion. Look tbm I spend that case when they brought me a Mitsubishi vehicle and well, in central locking some pestillos or solenoids work, which sometimes does not maintain them tend to get stuck, what you could do is disassemble the purts and make them a penetrating lubricant so that it soften a little and work as it should be. I hope my comment is used. Greetings ..


pd. The system is electric. So it is central locking ..

The closure is due to a combined pressure and depression system if the pump is running under the rear seat you must look for some leak in one of the doors actuators, trunk cap and fuel tank cover

Thank you very much for your answer but that was not the case because rather it was a defect of the small pneumatic pump that is housed under the rear seat anyway very grateful.
I greet you atte. Eduardo

Your response is successful, it turned out that the engine that injects air into the doors of the doors, it was grabbed due to having entered water and how your saying this engine is lodged under the rear seat to the DCH part.

So very grateful for everything. I owe you one. I remember an atto. Greeting.
