My daughter's 2006 Liberty has an intermittent turn signal problem for the last year or so. It started as the right rear just stopped working. Replaced bulb, cleaned socket and nothing worked. Replaced the light housing which includes the sockets and the circuit board and everything seemed to work fine a several months. Recently she started having intermittent failure of the same turn signal, but sometimes it works just fine or the right rear will work fine, but the right front does not. Could this be a problem with the flasher located in the fuse box? Short of trying to trace all the wiring for a short circuit, looking for some advice. Of course she has an inspection sticker renewal at the end of the month, so pressure is on dad now... Thanks in advance.
