I just fixed mine a couple of months ago. they weren't popping fuses but they wouldn't blink till I revved up so I took all signal lenses off,cleaned all sockets,replaced flasher with $2 unit from parts house.All works good now.It is possible to have a short in flasher but check wiring as other poster suggested.Lift seat and check wiring to rear sigs. It should'nt be anything expensive to fix.
