How do you replace 2006 Cobalt rear turn signal bulb?

Inside the trunk, on either side you will find a velcroed trap door. Pull this open and inside you will see two locking tabs that hold the black plastic mounting for all of the lights inside the rear lens, remove the connector at the bottom by wiggling it back and forth until it disengages. Then remove the mounting by squeezing the protruding tabs towards the cennter, replace the bulb, reseat the mounting and reconnect the bottom electrical connector.
