No back running lights
So I was having trouble with my 2006 Buick
rainier’s low beams going off and coming back on
with no warning. After some research, I believe I
fixed the problem. But then I had to replace a
brake light bulb in the back, I replaced both sides.
Now at night I have no running lights. Brakes, turn
signals and reverse all work, just no lights while
driving. I’ve checked fuses, what wires or anything
else can I check before getting pulled over? It is
my only vehicle so I don’t have time to be letting it
in a garage to be fixed.
