I have an intermittent problem that just started happening in a 1996 dodge caravan
the rear drivers side signal light works usually first thing in the morning , but then at some point during the day when I signal a left turn I get the rapid flash that indicates a bulb burnt out
the rear signal has stopped working ... break lights and other lights are all fine. I replaced the multifunction switch as well as the 3057 bulb to no avail, any ideas?

 

Try cleaning three contacts in the socket and using some dialectic grease on the contacts.
