Hello, I have a problem and I can’t open my rear left door anymore. when I open the central opening it doesn’t make any noise at this door anymore you just don’t hear anything. And when you pull the lever from the inside you also notice a resistance that makes me think that the locking is still closed. Now my question and that’s how I get the lining off from the inside ? or do I get difficulties there ? And then how do I go on ? how do I get the lock now? on ? Do I have an appointment at a workshop just afraid to come up with the high cost?!!!!!!! and wanted to see if I could not get it myself. what could be the mistake ? lock broken ? cable break ? or the engine from the central lock??? Thanks already in advance
