Haven't had any problems w/ my rear hatch latch (knock on wood), but... Have you taken the inner trim panel off to check the connection? I just had my rear hatch apart last week (put the E34 M5 Touring license plate filler on) & everything is easily accessible. Maybe give it a look- possibly the connector isn't all the way in- especialy if you have the new rear hatch harness already- Just a shot in the dark-Originally Posted by Steve N
What color E30 M3 do you have? Any mods?
Take Care!
