most likely it's the flasher i would try that

The flasher is in the same relay block as the blower motor relay. It is just off center of the steering wheel column under the dash, behind the knee panel.
It might still have a cover on it, so you will need to take a close look.

It is not the flasher if the hazards work, it is 1 flasher for both turn signals and the hazard lamps. It is in a relay block ( along with the blower motor relay ) under the dash, about in line with the steering wheel column ).

Try tilting the steering wheel all the way up, and test again.

The other quick test is to cycle the hazard switch a few times, to see if it cleans the contacts for the turn signal on the MFS,

it's in the auxiliary relay box behind the glove box.

13350 is base part number on flasher

for the most part its under the dash on the driver side give these websites a try www.autozone.co and www.alldatadiy.com if all fails stop by your local Ford dealership in the parts department and they will print you out pictures and diagram showing you where its located wish you the best Michiagn Man.

when they dont work, turn on the hazard flashers, or grab the hazard button and wiggle it. if they start working you will need the turn signal switch replaced.

The temperature blend door actuator is located on the right side of the transmission hump under the evap. case. The floor ducts cover it.

try to find electronic flasher under dash,some disassembly required,turn on hazard lights,that flasher is close to the one you are looking for.

Start by checking to make sure you have the correct size bulbs installed. If they are correct then replace the flasher relay. It is located Front seating area, driver side, under dash, mounted on top of brake pedal. If that does not cure the fast flashing, you may have a bad ground connection or the turn signal combination switch may be bad.
