turn signal not working

[btmslm]

i have a 06 ford explorer xlt and i have not had a right front turn signal for about two months now. the rear one works but blinks fast. the flasher on that side doesn't work either. we have tried replacing the bulb, didn't fix it. parking lights work. spent $120 at ford dealer for multifunction switch, didn't fix it, checked the fuse, it looks fine, any ideas? please

does the rear left flasher still work? if so, it could be a sever in the wiring to that corner.

yes the rear flasher will work
