I've got a '98 Civic EX.
The driver door won't open from either the inside or the outside.
It's warm here in Florida so it hasn't iced up.
The inside lock switch hasn't worked for along time or the keyless entry.
Anyone have a picture of the latch mechanism inside the door or have a fix for this?

 

I dont think that you can get the door panel off with the door closed. If you can, try and see if one of the linkages broke. If it did you might be able to find one at a junk yard.

I will try to get a pic up tomorrow if it stops raining here.
