I'm getting a new OEM headlight ordered for my 3rd gen, and i need a "How To" or some on how to replace the left headlight. It looks as if I have to remove the front grille like the 2nd gen.

Any links to how I can replace the headlight or some tips?

Go there to see how to remove the grill. Then remove the corner light by unscrewing the screw on top and pulling the corner light towards the front of the vehicle.. it will probably take some tugging before it will come loose.
Next, remove the filler panel thats between the headlight and the bumper ( it's rectangular ).
As for the headlight, there are 4 bolts holding the entire assembly on. Remove these and unplug the wire harness behind the headlamp assembly. Reverse steps for installation.

 

Cool, thanks for the info.
