That was great thanks for the information I just saved $150.00 bucks! I love this site

The left front turning light bulb turned black (blowen out) and is non-functional. Bought a replacement, raised the hood to gain access and was immediately baffled. How in this world are we to gain access to replace this bulb?

It is necessary to remove the front fascia. It is an intelligent design. I have had the luxury of doing about 5 vehicles in the past week, CTS, SRX, and STS are about the same. I think it is becoming standard of the industry and not just GM. Depeding on your relationship with your selling dealer, they may provide goodwill assistance and replace it under warranty. It would be worth asking.

how do you replace a bulb in the headlamp

To get the lamp out, the front fascia has to be removed. This is not that complex, it just requires the wheelhouse liners, the lower splash shield, the upper plastic push-pin retainers, and the bolts at the fender to fascia seam(accessed in the wheel wells)

Check your other post. If this is a HID lamp, it may not be just a bulb, you have a ballast to be concerned with. If it is just halogen, disregard.
