Basic question on 2001 Grand Marquis - I hope - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Hello everyone!
I just bought my wife a 2001 grand marquis. The headlight assembly and cornering lamps assembly have a ton of fog, yellowing, and water droplets in them. I want to buy some replacements on eBay and install them. Are these fairly easy to install? Are there any instructions out there? I know one of the first things to do with any new headlights, especially from eBay, is to seal them with silicone. So, before I order these things can you guys give me some pointers on how to replace them? I replaced the headlights and adjusted them in a friend’s mustang about 2 years ago and I remember that being pretty simple. Any help would be appreciated. I would hate to buy these only to find out that the whole front end has to come off to install them or something.
Thanks in advance!
Don

The headlights are VERY easy to replace. Open the hood, remove the black front cover in front of the radiator (3 clips), Pull 2 retainers behind the headlight and unplug the wires.

I think you are talking about just replacing the bulbs. I want to replace both headlight assemblies, and cornering light assemblies. Both are yellowed and leak. I will of course install new bulbs. I appreciate the help, and perhaps I am misunderstanding what you are saying and you are telling me how to replace the whole headlight assembly lenses unit and corner lenses unit. I guess I should say, I want to replace the lenses.
Thanks!

To replace the bulbs you only have to remove the upper panel. To remove the headlights you pull the 2 retainers. They're black with a bent top to pull them. Here's on a Crown Vic which are very similar. 1999 Crown Victoria - Headlight removal

So, to remove the assembly I would just need to pull that retaining strap. Looks pretty simple. What about the corner lenses, anything special I should know there. Much appreciated!
Thank!

For the side marker, there's a screw outside and a nut inside the panel behind the headlight.

Fantastic! Thanks so much. I can buy with confidence now!

Thanks for the help everyone. I just got the headlights in. How do you adjust them though? Or do they come preset or something? The mustang I installed headlights on had a hex screw at the top, these don't have anything like that. Thanks in advance!

There are 2 adjusters on each headlight. One for up & down and the other for side to side. They are thethreaded posts that stick through the clips in the back. You'll see a nut like on the ends. I believe they are 4 or 5 mm.

Thanks,
I took a look at my headlights and i see three posts. They rotate in many different directions as well. They have a ring on them. Is it a difference in models? I just don't want to pull these things out and end up with a mess on my hands. I appreciate any advice.
Thanks.
