How do you replace the headlight bulb in a 1996 Oldsmobile cierra?
The bulb is accessed from the rear of the headlight assembly. From under the car, reach up into the gap that's in front of the radiator. It's still pretty tight quarters, but with the proper manipulation, you should be able to get it out (I forget which way you have to turn it, and whether you have to push in while doing so). Then, you can get the bulb out to where you can see what you're doing, and detach the wiring. (Need I warn you about keeping the new bulb free of dirt and oils while you install it?)
