2007 STS, having trouble removing the red rear side marker to replace bulb (moisture got inside, from bulb seal I assume). Any tricks on removing the marker? Tried a really thin hook but nothing.

To get the lamp housing out you need to pinch together two tabs on the back. You'll need to reach up from underneath the car. Once it's out you will be able to inspect it to get a better idea where the moisture may be coming from. You don't actually need to remove the whole housing to change the bulb, but in your case you'll want to. The bulb is a W5W.
