Chrysler Repair: Chrysler 300C emergency flashers, chrysler 300c, rough pavement

Question
2005 300C emergency flashers tend to go off w/o engaging the control switch. Dealer replaced the F.C.M. module about a month ago. Thought this fixed the problem, but they still engage when I drive over rough pavement or just go off by themselves. Any suggestions? Don

Answer
the Hazard is on the switch back which could be a cause and then it is muxed to the cluster from there over the network.
SO u could be looking at the switch bank,wires,cluster,connection issue.I live in the Atlanta area I would be glad to look at it for u.
