Had a little problem pop up today on my Ebony.
I couldnt unlock the drivers door!
It unlocked and opened fine earlier this morning, but around noon when I was going to take off for lunch, it was a no-go. I couldnt even unlock it from the inside (WTF?).
I took it home and swapped cars and havent had a chance to look at it yet.
What should I look for?
Fuse?
Foreign object jamming the works in the door? (How would I open the door to get the panel off to find out)
Or its just mad at me for not driving it more often?
