Question about 2004 Cadillac CTS

2004 CTS Cadillac front passenger turn signal bulb is out.

I have a 2004 CTS Cadillac. The turn signal bulb is out on the front passenger side. How do I replace it? I have bought the bulb, but the Auto Zone person said I needed to jack up the car and go under the bumper to replace the bulb. Is it really this complicated?

Actually no you don't. Crank your steering wheel all the way to the right so yo have the maxumum clearance for your hands and arms in the front of the wheel well. Remove the plastic clips that hold the wheel well splash guard and pull it back enough to allow access to the interior of your bumper.
Replace bulbs as needed.
Yes, a jack is nice and makes it a touch easier to access, but I did this in an AutoZone parking lot during a cross country road trip.
5 mins tops to complete.

    Brilliant suggestion. I got to the bulb from underneath by moving the inside fascia rearward away from the bumper after removing three of the wheel liner fasteners as recommended by KMTANNER. Took 15 minutes. GX.

How to change front turn signal bulb in Cadillac cts


KMTANNER is correct for the 2003-2007 CTS. For the 2008+ CTS, you need to remove the bumper. The bumper comes off fairly easy, but there are a 2 hidden screws. Look for the youtube video on removing the bumper. I have a 2004 and 2009 CTS. I did both.

2008 CTS front directional not working?


Try replacing ALL directionals for the side that is not working properly. That fast blink in the back usually means bad bulb, but could also mean bad relay.

Can you elaborate? You say emergency flashers work, but FR directional does not. Does the bulb-in-question light when the E-flashers are going?

How do you replace a front turn signal bulb


I replaced the front turn signal bulb on my 2004 CTS. I removed about 4? screws holding the inner fender to the outer fender, just forward of the tire. Then you reach your hand in and find the socket. Twist the socket about a quarter turn to unscrew it and remove the socket. As I recall the bulb is pulled straight out of the socket.

A likely cause is a dirty / corroded bulb socket which is causing arcing & overheating the bulb.
