Bulb Failure Multiple Bulbs

Locate the fuse. Pull the fuse out. You should be able to tell if its blown.

How do you check for a failed/blown fuse? Do I need any instrument/tools, or can you just look at the fuse box and tell?

I got a Bulb Failure Multiple Bulbs message and my headlights are out, both dims and brights (parking lights still work), on my 2004 v70r, which is at 68,000 miles. Can anyone advise as to the probable cause of this problem? It seems to me that the chance of those bulbs burning out at the same time is small enough that the problem is actually electrical (could it be as simple as a fuse?), but is there a more specific message that would be displayed if the problem were a fuse or some other electrical problem, or would the message be the same regardless of whether its a bulb failure or a fuse or a short? Some other info potentially relevant to the diagnosis: It was a very hard winter on the car, which was in perfect condition and well maintained before the winter: Both sideview mirror covers have been smashed (one by a bus). The sideview mirror tilt controls still work, but in light of the multiple bulbs failure I wonder if its possible that water ran down the sideview mirror wiring insulation to somewhere where it has caused a short. That sideview mirror wiring appears well insulated, and the multiple bulb failure did not occur during a rainstorm or anything like that, but still I thought I should mention it. Also, my wife was in an accident during which the drivers door and drivers side rear quarter panel were dented and the drivers side tail-light was cracked (slightly but enough to leave a very small hole near the bottom of the tail-light). After that taillight damage, I started to receive a position bulb error, and one of the two lights in that tail-light failed, although initially I was able to get it back on just by smacking the tail-light with my hand (which suggests corrosion — not surprising with a small hole in the tail-light cover). Anyway, thats my sad saga. I was planning to get body work estimates this week, but the headlight issue is obviously more urgent. I dont currently have any mechanic or dealer here in Chicago that I trust, so Im concerned about being taken to the cleaners on this headlight/electrical issue and would greatly appreciate any potentially helpful information or advice.

BTW, Ive getting the position light error as well, on the driver-side tail light – tho there hasnt been any accident. My Volvo dealership told me it could be due to moisture (e.g., during a car wash). Sometimes tapping on the tail light did revive the bulb. But lately tapping hasnt worked. I hope that its just the bulb thats gone, not the wiring (or other electricals).

Difficult to say why the fuse failed, could have been many things. I will say that this isnt a common issue, but I also wouldnt worry about it unless it was a persistent problem.

It was indeed the 1 master fuse, the 15A, as Chriswb indicated! An easy – and extremely affordable – fix.

CAREFULLY pull the bulb (or you will drop it and be unable to retrieve it) and just replace it; you will have to in the near future anyway.

Interesting. The exact thing happened to my 04 V70R (77,000 miles) yesterday! Low, high beams and DRL all went simultaneously, and I got the same messages you did. Very suspicious. Im glad I googled the problem and found this post. Ill check the driver-side fuse box.

Will report back if its indeed the fuse.

I like that Volvo has included a pair of tweezer to pull out fuses.

Solved (I hope): It was a single master fuse — fuse 1 in the fuse box thats near the drivers left leg — which blew and cause the dims, brights, and DRLs to all fail. I do have a lingering fear that there might be a more significant problem that caused that master fuse to blow, but until it blows again I can hope that it was just a fluke. Does anyone know the expected lifetime of this fuse or what might cause it to fail before the end of its expected life? The car is 7.5 years old with 70k miles.
