Good afternoon, here is the info you requested:
NOTE: Headlamp lens fogging is a normal condition and does not require service unless excessive or continual. Moisture will vent from tubes or vents located on the back of the lamp.
NOTE: Once the crossmember is loose, take care not to scratch the fenders.
CAUTION: Do not touch the glass of halogen bulbs with fingers or other possibly oily surface, reduced bulb life will result.
So to summarize, you do have to remove the headlamp units and inorder to do that the upper radiator support has to be removed or moved out of the way and the front fascia (bumper cover) needs to be flexed outward.
If this answers your question then please press ACCEPT so that I may be paid for the time spent helping you. If you need more help then please let me know. Thanks
