My 2004 S60 passenger side low beam is out and its not the bulb and the fuse under the hood is getting no power- so Im assuming it may be the relay under the driver dash the in the cem. There are three and they are all the same --9442190A is what is marked. Is this a relay, a shunt or resistor? and is a 94442190A the same as a 9442190 resistor I see on some Volvo parts sites for the S60. They look OK but I'm hoping that's the problem- any thoughts?

 

check for voltage at your light switch
open the drivers door
pop off the fuse panel and pushing from behind the whole switch assembly just pops out
2 clips at the top and one at the bottom (its the slightly tricky clip)

since your still getting your drivers side light the switch is unlikly but i thought ide metion it

other than that inspect as much of the wire harness as possible

 

I believe the relay is internal to the CEM/central electronic module. You may need a new CEM, I've seen it before

 

It was the bulb connection, it the plastic was brittle and the metal connections came loose.
