On the headlight itself, there is a gasket surrounding it. Use a small plastic pull tool and some Wd-40 and gently pry the gasket all around the headlight to let the lubrificant penetrate between the gasket and the housing. Wait 5 min and try again
Don't forget to wash off the wd-40 when done. Nasty chemical
Thanks to all for your suggestions. I've tried them all, but still no luck. I just bought the car last week and this is my first project. I noticed a tiny bit of paint on the lens and am wondering if it was hit and the positioning tracks are crooked. (Carfax didn't indicate any accidents) I'm going to jack it up, pull off the wheel and see if i can get to it through the wheel well.
For those having difficulty removing the headlight assembly, it is possible to access the bulbs through the wheel well. After removing the wheel and fender skirt, I was able to get at the door covering the bulb housing and replace the bulb without ever removing the assembly.
I broke the piece of amber too but still holds to the clip, just use extra force sliding it out while pulling from the top end of the assembly. The tool for unlocking the headlamp is with the tire kit (black pouch).
