The rear passenger blinker/brake light on my 2005 Dodge Grand Caravan is not working. Upon inspecting the lamp socket, I noticed that one of the contacts was burnt. The lamp snaps into a socket, which in turn snaps into the housing. There are no wires on the socket, just contacts that mate up to contacts on the housing. I contacted a dealer and was told that I had to buy the entire tail light assembly. I've found a Dorman replacement part number for the socket, but they appear to be out of stock. The part number is 923-040. Does anyone know where I can purchase one of these? Thank you in advance.
