You will be required to remove the front bumper to replace the headlight bulbs on your CTS. I am wondering how many miles you have on this as you may be under a factory warranty. If you post your vin# XXXXX can tell you. If you would like I can give you the info to replace the headlight bulbs. Feel free to contact me with any questions!

I followed faschia removal instructions but was still unable to remove it.I removed all screws as described in diagrams but faschia would still not budge.are there any additional srews underneath faschia or elsewhere I would need to remove?
Expert:  Carhelp4u replied 9 years ago.
Did you loosen them at the wheel liner and also at the radiator core support? I cannot say that I have had one of these apart as of yet.
Customer: replied 9 years ago.
Yes I did. Just as described on diagram I got sent. Top part of faschia does come off when I pull slightly but bottom seems screwed down still.
Expert:  Carhelp4u replied 9 years ago.
Sorry for the delay, I am going to see if I can find a better illustration of this car. I am not sure what else might be holding you up. This is the way gm gives their instructions to replaced the headlamp. I will be in touch. Thanks for your patience.
Customer: replied 9 years ago.
Thanks..by the way, I noticed there are plastic snap on screws like the ones along wheel liner all aalong bottom of faschia-would those be screws I need to remove still? Thanks
Expert:  Carhelp4u replied 9 years ago.
Yes they would. The first instruction set I sent you stated, Remove the wheelhouse liner. These would be holding you up some I would imagine. I did get a better picture of the front bumper, bur my scanner seems to have broke. My only other concern would be the tabs at the bottom of the lower grille. the illustration shows about 6 tabs and I cannt seem tfind where they actually go. I am figuring that they either go into the grille, which wouldn't cause you a problem like you are having, or possibly they go into the bumper absorber which may cause you a bit of trouble. I will try to get the picture scanned so you can see what I mean. That is as soon as I fix my scanner. I will keep in touch. Thanks again for your patience.

I thought i'd take pics of my car's front and bottom faschia so you could get a clearer picture of what my vehicle looks like. Is there an email i can send you jpeg pics to?
Thanks
