I had a similar problem with my S70 and discovered the headlight switch was defective. The switch had actually begun to separate causing the contacts for the tail lights not to make contact. Try having someone observe the tail lights while you push on the headlight switch. If the tail lights begin to work, replace the headlight switch.

To replace the headlight bulb on a 1999 Volvo S70, first, ensure the vehicle is turned off and the headlights are cool. Open the hood, locate the headlight assembly, and disconnect the electrical connector from the bulb. Remove the rubber cover (if present), then twist the bulb socket counterclockwise to release it. Replace the old bulb with a new one, making sure not to touch the glass with your fingers, and reassemble everything by reversing the steps.

To replace the master window switch on a 2000 Volvo S70, first, disconnect the car battery to ensure safety. Then, use a flat-head screwdriver to gently pry off the plastic cover surrounding the switch panel. Remove the screws securing the switch panel, disconnect the wiring harness from the back of the old switch, and then replace it with the new switch by reconnecting the harness and securing the panel back in place. Finally, reattach the plastic cover and reconnect the battery.
No, you do not need to remove the bumper. here is a video on how to change your headlight really easy. http://youtube.com/watch?v=ieXVCTWQHSY I did it just to see how easy it was and it was pretty easy.
No you do not, there are 3 bolts you need to remove in order to take out the headlight. Don't remember off the top of my head where they are located but you should see them. I think they are 12mm bolts.
Yes, they will.
Yes, the 1998 Volvo S70 is equipped with a fuse for the headlight wipers. The fuse is typically located in the fuse box, which can be found under the dashboard or in the engine compartment. If the headlight wipers are not functioning, checking the corresponding fuse is a good first step in troubleshooting the issue. Always refer to the vehicle's owner's manual for the specific fuse location and rating.
