Car is a 70 Mach I. Supposedly the door was working fine and now suddenly it won't open, at least from the outside. Haven't had any real time to look at it but was wondering if this was a common problem or some basic things to look at. If I have to take the door panel off would that involve removing the seat since the door is in the way? Owner says he thinks "the door handle button stopped working". :shrug: Any ideas?
