Mike,

It's hard to say exactly what you door problem is ... but when my son's 240 Turbo pass. door refused to close and stay closed ... I swapped it's door latch with one from my dead 80 240DL. As I recall it was a quick fix ... just a couple of allen head bolts holding the latch to the door. Worked like a charm. If you have access to a spare latch I'd try that first. As I recall it took about five minutes to make the repair. I did put the Turbo latch onto the donor just to see what would happen ... it wouldn't close and latch ... so in this case that was obviously the problem. You might be able to repair the latch but if you can find a replacement, I'd go with that and save yourself some time and trouble.
