So
My left turn signal doesn't work at *NIGHT* anymore... Instead if blinking it stays lit...
It's a 2005 F-150 FX4
Everything works fine during daylight...
And if I turn my lights off (dim) after dark everything works fine...
My 4 ways also do not blink after dark... But are fine during daylight....
I haven't done any work to the truck recently.... It just stopped working at night about 2 weeks ago...
Any thoughts...???
