Hi guys. I'm having a problem with my rear signal/flashers. Both rear signal lights failed on me, however the front works fine although they flash at double speed. I was told it was probably the flasher relay, or the fuses, but checked the fuses and bought a new relay and still have the same problem. Also replaced both rear lamps. If you can, please point me in the right direction. Be gentle though, I am a rank amateur mechanic and am doing this out of budget necessity and the desire to be self sufficient. Thanks.
