Headlights problem
 

My 1999 Volvo s80 has headlights problem they just went bad I cheek all the fuses and bulbs and still not working both sides are dead.
Thanks for any help

Lose the low beams only? If you checked the fuse in the passenger compartment, AND the two under the hood, and they're all good it is probably the resistor shunt on the CEM. It's under the dash on the drivers side, left side of the footwell. The low beam one is the bottom one. It's about 1 1/4" wide by 3/16" thick blade looking deal with 4 prongs. Swap that one out with one of the ones above it (for turn signals). They're all the same. If you get lights, then you need to replace the bad shunt. They're available from the dealer for around $6. I believe it's part #9442190

Maybe the shunt in the CEM went bad or is not making good contact.

They tend to burn and cause a bad connection.

I am having the exact same problem right now. I am going to check the shunts tomorrow. Thanks for the info guys.
