I have a 2011 f150 with 2014 oem HIDs with morimoto harness. One of my bulbs failed so i ordered a new set of bulbs. After swapping in the new bulbs the low beams and low beams only do not work. I checked the fuses located in the passenger side foot well, and even swapped a fuse to make sure its not the fuse. Re did all the connections and even added di-electric grease to all the connections. Went as far as putting back the old working bulb to check if it was the new bulbs, but no go. As of right now i am not sure what it could be. The hi beams will stay on with no issues once i shut them off i can see that the low beam is on for half a second and then shuts off. Any help would be much appreciated. I will call retro fit source on tuesday since its long weekend!!

From my past experience, could be a harness issue or more specifically the relays.

I went thru 3 different harnesses, and each time it was a different problem. One time, my low beams would not turn on, but highs worked fine.

well i hope i can get a new harness asap

Well i got the new morimoto control and still the same thing, i am wondering if it has something to do the multifunction switch or anything with my truck. Anymore input would be great if anyone has any ideas

Dont think that it is the wiring harness, i still have the old halogen headlights and i plugged her in and the low beams still did not work. Now i am leaning more towards something with my truck.

Did you just replace the bulb or did you replace the bulb AND ballast? The ballast you have may not be compatible with the new bulbs you are trying is all

Doesnt matter... He just said he tried putting his halogens back in, and they do not work on low beam either.

OP, keep us posted as to what you find out. Im stumped now...

****!!! I Just replaced the multiswitch and thats not it either, parts guy at ford told me worst case scenario its the pcm and thats costly. I have done everything that i am capable of doing, gotta take it to a mechanic now.
