Headlight Issue Our dealer told me to replace my front headlight bulb that I need to remove the front bumper. This this true??

Remove fender well trim ( a few screws)
Remove front bumper COVER (not the bumper- the plastic cover)
About 14 screws. Mostly on the underside, get a creeper, and a few
on the top.

Remove the (left or right side) Headlight assembly ( a couple more screws).
One assembly contains the headlight, turn signal and running light. Unplug
the electrical connector from the assembly. All bulbs remove from the back
of the headlight assembly. Headlight is held in place by bail wire, smaller
bulbs are 1/4 turn.

You can remove the inner fender well and gain access to the bulb with a little luck and creativity. Removing the wheel will make this a little easier. Make sure you check the connector as they have issues with them melting.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

first if you are changing the bulb only and it is a HALOGEN
there is a round acess hole in the inner fender remove it and change the bulb
if you have HID lights or are changing the head light assembly then you have to remove the front bumper facia
hope this helps
hope you have HALOGEN lights

I will be working on my CL and keep you posted on what to do.. shouldn't need to remove the bumper.

To remove and replace head light bulb labor time per Mitchell labor guide 1.4 hrs each X shop labor rate.Find out what there labor rate is.Head light bulb high or low beam (Halogen) O.E run about $17.00 each.

if you have the regular headlights(not the HID) there is a TSB for that at the dealer and they will fix it for free as long as you are under the 36000 miles,,anyhow to get the headlight out you need to remove the front bumper cover,,pop the hood, remove all the pushpin that hold the plastic panel on near the front area then remove the plastic cover,,,,,then there are some phillips head screws along the front of the top of the bumper cover take these out,,,,now remove both front wheels,,remove the bolts that hold the inner fender liners inplace there are some in front and under the lower bumper cover take these out too,,,,then under the front bumper cover at about the middle there will be 2 bolts i think 10mm remove theses to,,,,now where the side of the bumper cover meets the fender inside there are 3 bolts on each side remove these i think they are 7 or 8mm and then pull the bumper cover off,,,if you have fog lights disconnect the plugs,,then you will see all the bolts holding the headlight in take them out and then it comes out,,,,i know its alot of work just for a headlight ,,,,

You are supposed to remove the front bumper to take the headlight out.

However if you remove the vertical philips/10mm bolt at the far back edge of the bumper and a few of the upper 10mm bolts on the bumper cover, you can pull the bumper down far enough to access the one hidden bolt on the side of the headlight.
Just be careful you do not damage the paint when doing so.

Well according to my mitchell manuel you don't have to.here is the procedure.
1. open the hood.
2.Remove the push-pin retainer's that secure the top of the upper facia and grill assembly to the upper tie bar to allow the upper facia and grill assembly to flex forward.
3. remove ther bolt and push-pin retainer that secures the top of the headlight assembly to the upper tie bar.
4. Gently pull the upper facia and grill assembly forward to access the bolt on the inboard side of the headlight assembly
5. Pull the headlamp assembly straight out to disengage the the snap in retainer at the lower outboard back surface of the assembly. Turn the assembly so that the inboard assembly clears the front facia.
6. pull the assembly out and away from the veh.From there you'll be able to access bulbs.
be careful not to touch the bulb with fingers or oil in skin will blow bulb.
Good luck.

To replace the headlight bulb on your cts, it is kinda a pain. You pretty much have to take the whole front bumper off. First remove all of the push pins that hold the air deflector on the bottom. Next remove the pushpins that hold the grille to the tie bar. Now remove the front fascia extension. Remove the bolts that hold the bumper to the fender. Once all the bolts are out that hold the bumper on, you gently pull out on the bumper, but be careful not to crack it. If the windshield washer hoses are connected to it then you need to disconnect them, but you may want to plug the line so you don't loose all the washer fluid. Next there are two bolts and a nut that you remove to take the headlight out, and remove the connectors that go to it.

I know your frustration! I cannot believe the complexity of changing the headlights. Chevy has tried to make this a dealer item only just to change a headlight bulb. I will try to explain the procedure unfortunately I do not have photos. First you will need to remove the wheel well liner (two bolts and two plastic push pins). Pull the wheel well housing back (you will need to turn the wheel/tire to gain access) and using a 7mm socket remove the plastic support piece that holds the bumper in place (two bolts). Pull the corner of the bumper down until you can locate the bottom bracket of the headlight assembly that is held by a 10mm bolt. Remove it. (Oh did I mention this is a two person job!) Next move to the front of the vehicle (hood up) and remove all the 10mm bolts holding the upper part of the grill (I think there are eight of them). Now remove the obvious top two bolts on the headlight assembly! With two people - one to work the headlight assembly and one to push down the bumper and pull out on the grill assemble, slowly and carefully pull the headlight assembly straight forward. You will need to be mindfully of the small tabs on the headlight assembly that like to get caught on bumper/grill. If you are just replacing the bulb, you should be able to move the headlight assemble far enough forward to gain access to the bulbs without totally removing the headlight assembly. What a ***** job! SHAME on GM.
