You will need to buy to special tools to do this job. i recommend using a qualified mechanic. Your going to need to replace 3 plastic parts that always break. If you want to do it just post back the update for helping all of us here. Thanks.

Check the fuses for headlight as both headlight cant go bad at same time, and with alternator installation only thing can blew with wrong connection is fuses.

A MacPherson strut as found on your front suspension has a shock with a concentric spring (the spring is around the shock). You have struts in front. You have shocks in the back. You have an air pump on the back shocks. The purpose of the air support is to compensate for if you put a lot of luggage in the trunk. If your drivers side front is slanted down, I believe you have a bad/sagging SPRING, not STRUT. The FRONT strut controls MOVEMENT not LEVEL. You have computer controlled air shocks in the back that are filled with a compressor behind the RR wheel. If you have a leak in the rear, both rear shocks will drop not one side. Tell us the history of this car, has any work been done to the front suspension to permit/allow the 20" wheels? Have the springs been CUT/Modified? If you are sagging in the front, there are very few reasons for that.

i wanna know how do i access the headlight bulb as it has burned out i have a 2005 Cadillac sts. any advise is good advise thanku
