all else on car works perfectly (other shoe drops??????)
waring 1: no scan tool, you will fail (99%)
is battery fully charged to 12.6vdc rested or at 10v?
all 4 corners dead?
not working means dead?, flashes too fast/slow or dim? or they stick on? (5 modes to fail not counting L/R and haz)
do the hazards work? (prime evidence and not stated)
most cars before 2007 have fuse marked TURN.
but not this car... its not at all like older cars....
did you scan it first
after the fuse tests? any PCM scan tool.?

the FSM chapter 8L shows the huge list of errors the lamps can fail. DTC errors.
in fact 8 blinker codes, ! DTC errors,
there is no fuse, just for turns,
(trailer lamps fuse 19)
read this excerpt from the FSM book.
The turn signal system operates on battery current received on a fused ignition switch output (run) circuit so that the
turn signals will only operate with the ignition switch in the On position. The hazard warning system operates on
non-switched battery current received on a fused B(+) circuit so that the hazard warning remains operational regardless
of the ignition switch position. When the turn signal system is activated, the circuitry of the left multi-function
switch and the FCM will cause the selected (right or left) turn signal indicator, front park/turn signal lamp, front side
marker lamp and rear tail/stop/turn signal lamp to flash on and off. When the hazard warning system is activated,
the circuitry of the hazard warning switch and the FCM will cause both the right side and the left side turn signal
indicators, front park/turn signal lamps, front side marker lamps and rear tail/stop/turn signal lamps to flash on and
off. The Front Control Module (FCM) can also activate the hazard warning system lamps.
the module front control MFC, runs this
and it uses fuse 18 , if 18 blows the module goes off line and vast things fail and huge numbers OF DTCs store.
and fuse 27 MFC
MFC needs these fuses good.
keep in mind nobody has MFC internal schematics...so........
this module drives left and right side front and rear.
electronic drivers, not fuses.
the MFC is here.
the fuses are 12,13,18, 20,27 that power MFC.
ground this end.
