It’s normally either the box type sensor mounted on the side of the cab mount or the lock not fully home. WD40 and a screwdriver moving the lock open and closed will sort it out, if everything looks ok with the lock then try the sensors. Remove the plug, get a bit of wire and stick it in both the terminal holes to join them together. If the light goes out you’ve got a dodgy sensor . Don’t forget there’s one either side, check them one at a time.
It’s normally one or the other of these things.Sent from my iPad using Tapatalk
