Break Lights and turn signals Not working
30

Asked by Joey Jun 13, 2019 at 08:17 PM about the 2009 Ford F-150 Lariat SuperCrew 4WD

Question type: Maintenance & Repair

Good Evening,

I have 2009 Ford F-150 Lariat 4x4. Three days ago the turn signals started
blinking faster than normal. I found out that my back, left and right break
lights and turn signals are not coming on. But i check my manually and
checked number 6 fuse and i didn't see anything wrong with it. Although to
be honest, not entirely sure if i could either way.

What are some option that i can look into or might be causing this problem?
Thank you in advance, trying to fix this by myself. Kind of low on the funds at
the moment. So many thanks in advance

You have to use a scan tool and reset your fault code to get it to blink normal after replacing bulbs. I have a 2012 F150 XLT and after replacing bulbs, it basically pops a fault in the ecu, and until it is reset the computer thinks it is still burnt. Now, if you replaced with and LED bulb as I did all the way around my F150, they will fast blink unless you also install the resistor fuses that are sold seperately. LED require less resistance to operate, therefore the truck thinks the bulb is still burnt. I never bought the resistors, I just deal with the fast blink.
