I have an '04 Colorado and I got some issues with my driver side turn signal/parking lights. When I test my parking lights the bulbs are on, when I put the car in drive just the automatic "parking" lights come on my driver side is completely out (both bulbs). My driver side turn signal is also flashing quickly and bulb does not work. I replaced both bulbs. Trying to figure out if i can fix this issue before taking it to a shop. Thanks.
