With me it was/is a connection issue. Same situation, same bulb. Pull your
tail light assembly and pop out the bulb holder. Turn on the key, and then
set your turn signal to left. Now remove and replace the bulb in its
socket. Does it work when it hits a "sweet sport?" Mine does. Guess I am in
for a replacement lamp assembly.
