I have a 1995 300Tdi Discovery and have a rear passenger door that won't open. I live in a place where the car is constantly subject to a salty atmosphere and in bad weather gets sprayed with sea water. A couple of months ago I managed to take the inside panel off the same door when I recognised the door seemed to be getting more difficult to open. I sprayed the entire lock mechanism with WD40 and it did the job. The door was easy to open and apparently back to normal. However I am once again facing the same problem only this time I got no prior warning that it was going to give up. The door catches won't open the door either from the in or outside so in effect I'm unable to get the door open.
I have managed to get the panel off the inside of the door again and given it a good spray with the WD again, but so far its done no good.
Has anyone got any ideas on how to put this right.
