I've had a problem that has slowly been developing with my '94 Legacy. The driver side door is becoming difficult to open with the interior handle, however it opens easily with the outside handle, so I know that the latch isn't gummed up or binding.
I'm thinking that there must be a linkage that is worn or stretched, and the interior handle hits its limit stop before fully releasing the latch. (That's just my theory...)
Has anyone had this happen before? Is it difficult or are there any guides on how to take the door panel off to check this out?
