Turn signals not working on 1996 Chrysler Concorde?

This happened on my sons 1995 Concorde. We thought it was the turn signal flasher, located under the sterring wheel. It is a black box with alot of wires coming out of it...kind of hard to get to in the small cramped spot. We replaced it and is still didn't work. Took it to the Chrysler Dealer and it turned out to be a wire that had came loose from the battery and the dealer charged me $70 to show me where and to hook it back up. The following are the directions I got from another forum I go to when I need Help. "Remove the black panel from under the driver's side dash (heater duct) and look for a white plastic box between the column and the parking brake, the flasher is a square shaped and about 3" long and made of black plastic like you found out with a 4 or 5 wire harness connection hooked to it (also black), you will need a small screwdriver or a key to slip in between the flasher and it's mount to unclip it and it will slide off the mounting tab. Aftermarket Flashers will not have the mounting slots for remounting, you may need to get a replacement from the dealer or a used one at a wrecking yard if you want to mount the replacement in the same location. Be aware that some models have 4 terminals (usually 93-94 models) and others have 5 terminals (95-up), get the replacement with the correct number of terminals as they do not interchange. I included some digital shots of mine in my LHS but they are in the same location for the Concorde too, might be a little fuzzy but should give you an idea on what you are looking for. The panel that must be removed to gain access And the flasher. Note mine is a 4 wire, yours may or may not be a 5 wire."
