If the bulb are OK, I suggest check "underhood" the FUSES (page 133 and next) of the Volvo S40 Owners Manual; keep in mind that you have fuses for "low headlamps left and right", position 9 and 10...



Hope helps.

wow just wow.

Check the Power Lead to the switches, if you have power it may be a corroded switch, a common problem and easy to fix by soaking the switch with WD40 and working it back and forth until it makes contact every time. Do this with the Power Off to avoid shorting the switch and clean up with a paper towel. If this does not work you will need to check the relay.

Sounds like you need to replace the bulb.

Have you had the fault codes read? If not do that first.

I had same issues on my 99 S80, turned out to be the spline gears on the end of the CV Axles that send signal to Wheel Speed Sensors. Their is one on each wheel, but the ones that gave me all the issues where only the front two. Problem was had to replace the entire CV Axle to be able to get new spline gear, but was only about $60, so was worth it.

The fuel pump relay is underneath the US steering wheel (i.e. on the left side of the car). You will need to take off the trim piece under the steering wheel (4 screws, philips head). There is an electrical panel a little ways in with four or five cubes plugged in. The green one is the fuel pump relay. Part#

Bad connections/wires or corrosion in them, charging system too weak, light switch going bad.

Most likely it is a blown fuse.

the may be caused by a misfire,the first thing to do is scan the computer for any stored codes as these codes can help a great deal, so start with the scanning first, auto zone and some other part stores will scan it for free ,just write down the codes and we will go from there.
