How to fix a f150 fast blinker 

Great job & video. I just had the same issue on my '02 F150 with the left turn signal hyper flashing and NOT working. Turned out to be the left rear upper bulb on the '02 F150 ( Bulb #3157 ). Changed the bulb out and woo-lah, all fixed! Thank you for posting!!

Oh boy this is great read on a forum it was the left rear usually you are the first to say check them all. I will go and do that now I have no indicators on the left rear and I thought strange not a bulb for both of them to be out.. Thanks again. Edit front works fine maybe it is the wiring will check it out Thank you

Got the same problem. Replaced both bulbs and then tested and worked fine. When I drive the truck the next day or want working again. Got any suggestions? It's done this twice. 2001 f150

How did you remove the grey piece of the conector and where can i get it ?

Thank you so much bro, God bless you

Why is it not working when you put new bulbs in you reverse the fuses reverse the relays Estelle you have the rapid flash and left rear does not work

Is there more than 1 fuse box and which # fuse is there a fuse for each light?

Actually, to loosen the bolts, you turn them the Left way! ;-) To TIGHTEN them, you turn them the Right way! (I gave you a Like to make up for my good-natured trolling.)

Needs to let someone video and use both hands
