Renault Master Sliding Door Adjustment
Ha ha not my usual type of answer but had the same problem about a month ago at the bottom of the sliding door is usually 2 rollers one at either end they adjust up and down by using a screwdriver the adjust screw is on the end or on the side of the door you may only see a screwdriver hole adjust it down move the slider to the middle of the slide and lift it up and the bottom of the door should lift outwards toward you this will allow the top of the door to come out of its slide area also.
