This may be similar to what I've read on other posts, but I'm not sure.
One of the rear doors won't open. The lock knob and the handle move without any resistance. It started with the lock knob not engaging when I unlocked or locked the car. I could push it up and down manually with no problem (solenoid gone, I guess). Then last night the interior light came on (apparently it thinks the door is open) and now the door handle and lock knob move but don't engage anything. The door is closed and seems to be latched.
What's that all about?
