First of all you need to check your bulbs? If the filament seems ok you new to work your way back up the loom, making sure there is no obvious damage. Secondly check your light fuse, this will be located in the engine bay fuse box or the cockpit, use your user manual to locate. If the fuse is ok, check visually and if possible with multi meter, I would suggest checking relay switch in engine bay. If this is ok then check your light switch/stalk.

Ask the dealer where your fuel power switch is located and turn it off. some turn off when you push them in. to turn it back on you push it in and it stays in. after you have located the fuel power switch and have turned it off, turn the engine on til it runs out of gas and turns off. it will run out of gas because you have turned the fuel pump powr off and the engine has burned the line fuel that went in to the engine. after the engine turns off, crank the engine for about 7 seconds. This will remove all the fuel pressure in the line. Your fuel filter will either be mounted under the car or on the engine fire wall. after you have located the fuel filter remove the two clamps (they may be metal or plastic) Take your time and watch how you remove them and you will reverse the order you used to remove the fuel filter clamps and fuel filter. It is a good idea to purchase new clamps with the replacement fuel filter and use them. Ask the dealer to explain how the clamp is removed and installed. He can demenstrate by illustrating it with the new clamps and fuel filter.

If there is a blinking car icon with an "X" over it. This icon means the Immobilizer has been activated and hence won't allow the car to start. It could be due to a bad SCU, Start Control Unit. The SCU is actually the ignition switch on these cars.
Most of the time it's triggered by the anti-theft system..You can try this trick i learned that the dealers won't tell you...try locking and unlocking of the doors five times with the remote to reset the immobilizer and see if this helps.

If the motor runs as you push the switch and keeps running till you stop the drive in the motor or the regulater has broken. You can try to manully close the window and then push the switch to see if it'll ingage. Opening the door by removing the door panel, work the switch to see what's not working. If you haven't worked on the interanl or car doors before at least get a manul to see the procedure and refer to the pictures as you can break it still further or hurt yourself inside the door.. Auto parts stores online sales catalogs will show you what the parts look like and how much they cost. Many Volvo's aren't covered very well at parts stores and you may have to get replacemnt patys on ebay to get a reasonable price. wreaking yards are spotty as these days they have to crush cars soon after they get them per enviromental laws.
