Replacement flashers are known to be lighter weight than the original. Installing a heavy duty flasher should solve the problem.
most likely would be a bad turn signal flasher
no both systems have a separate flasher
location of flasher relay ford 150 2004
On a 2001 Ford F150, the turn signal flasher is located in a relay box on the passenger's side of the steering column. To access it, you must remove the panel under the steering column.
Check fuse and turn signal flasher relay.
fuse If your flasher goes bad, You can still have flashers and no turnsignals. I would change the flasher after checking the fuse. == == If you have an adjustable steering wheel, try adjusting up one click. There is something about the setup that causes a wiring short.
The turn signal and emergency flashers are on a bracket together under the dash right about where the gas pedal is. The bracket can be lowered by putting a screwdriver into the clip and releasing the little catch. Remove the little cover over both flasher relays. The larger flasher is the turn signal (my 98 flasher was blue) and the smaller is the emergency flasher. I found mine by turning on the flashers and just following the clicking sound.

The hazard flasher is in the fuse box by the driver's left knee. There's a panel right underneath the steering wheel. It's the round, silver cylinder.
It's not a fuse. It is a flasher relay that operates either the signal lights or the emergency 4 way lights.
change the turn signal flasher flasher could be a fuse
The "flasher" module is located beneth the steering column behind the large plastic knee sheild. (comes off with two hex screws) it's behind the metal shield on the left side, should be connected to a bracket that is anchored to the frame
Only 1 fuse for turn signals--if others are working could be a bad flasher, bad bulb, or problem in steering column
