pop the hood. locate two long metal pins - one goes in horizontally, one goes in vertically. Pull the pins and the assembly comes out. remove top rubber cover. Unplug bulb. Remove. Replace. Repeat.

Check your relay switches under the hood fuse box. They should be a light grey from factory, they are about 1 x 1" in size and there are a few in there. Pull one out at a time and if they look brownish or yellowing replace. Go to Napa or Auto Zone for $15.99 a peice that most likely will fix it.
