F150 2011 Signal switch ISSUE HELP
 

OK I have a 2011 Ford F150. MY left flasher has been blinking very fast so I changed all bulbs, I checked all fuses, I changed the switch, checked the relays and still when I try to turn left it flashes fast. I looked under the truck there is no exposed wires. What else can it be??? I cant afford to take it to Ford they just like to bend you over and charge lots. :eek:
