Drivers door sensor not working, doesn't show that the door is open on the dash so the van locks the doors on the timer - dangerous for locking keys in the van. Tried WD40 on the catch, no point, didn't work. Bought new mechanism off ebay and fitted it today. Top tip, buy some multi spline bits before you start, you'll need torx bits, a torx bit on a long stem, 10mm spanner and long nose pliers plus a flat trim remover and electricians screwdriver. Took me most of the day. See you tube to remove trim. Another tip, 2 round plugs in metal door inner face, drop window until you see bolts on window base frame, loosen them, lift the window and tape it up out the way. You'll need to remove the door lock to release the handle cable too.
