On the 98 Silhouette, the PCM should be located in the air filter housing.

The first thing i would check is all 4 abs sensors at the wheels.You can do this with a volt meter set on ac voltage and spin the wheel if it generates voltage at all on the meter its good.
SOURCE: How do you change a headlight on a 2001 oldsmobile
I don't know if you mean the headlight bulb, or the headlight.
When you open the hood and look at the headlight assembly. At the top between the turn signal there is a black plastic wing nut. Unscrew that wing nut to remove the side marker light. After removing that nut persuade it to slide forward. That's the only thing that locks it in. Untwist the socket to replace the turn signal bulb. Since that is out now...There are two more Wing nuts just like the first one that hold the headlight assembly in place. (The black plastic piece the headlight is mounted to) Remove these two wing nuts and lift up on the whole assembly. Those are the only things that lock it into place. Once you slide it off the studs the wing nuts were on. Unplug the plug from the back of the light (use a flat screwdriver to lift the tab a little). Twist the round plastic ring that holds the bulb in. The bulb should pull out now. Don't touch the new bulb with your fingers as it is a halogen bulb and the oil on your fingers will cause a hot spot on it, causing it to fail SOON. If you happen to touch the glass part of the headlight bulb, clean it with rubbing alcohol. Reverse the steps...go eat dinner.

SOURCE: 03 Oldsmobile Silhouette 3.4L Starter stays engaged at times.
Sounds like time for a new starter. While it could be electrical, in that the starter circuit is remaining engaged, more than likely it is mechanical. As the starter wears, you get play in the starter gear. Replacing the starter should take care of it. If you have recently had the starter off or replaced it, it could be misaligned, causing a similar problem.
