When was the headlight relay added to the Volvo 240?
Same as Bosch PN 0332015001, 0332015006, or 0332015012. Beginning in 1986, Volvo added this “main headlight relay” to the 240. Prior to this the 240 used only the dash switch to turn on the headlights and then the well known high/low beam step relay under the hood.
How does a step relay work on a Volvo 240?
So with this step relay, one click latches “ON” the low beams. And another click latches “OFF” the low beams and latches “ON” the high beams. In a 240 the latch function is activated by a GROUND signal, which is created by pulling the high/low beam lever.
Where can I find locations for Volvo relays?
Here are some diagrams I’ve collected showing RELAY LOCATIONS for Volvo 240, 700 and 900 models. You will find a fair amount of information on the internet about this subject if you search, so I will be brief and offer some basics.
Why are the relays on my Volvo not working?
Relays made for Volvos are mass-produced and the soldering on the circuit boards is not the best on some of them. After many years of use, lots of heat cycles, etc, these relays will often become intermittent or fail. Most of these failures can be traced to a solder joint or two (or three) that has become cracked.

Is there a turn signal when headlights are on?
That’s one issue…next problem is the no front left turn signal when headlights (and all the back lights that come on when you turn on headlights) are on. I plan to check if turn signal doesn’t come on if i just put parking lights on?
What causes voltage drop when headlights are on?
When the headlights are on they are causing a voltage drop to occur across the ground to them due to a bad connection which causes a voltage drop to occur when current passes though a resistance.
