First thing you do is turn off the power to that circuit. Then replace the fuse
The power receptacle fuse on a 2007 Volvo S40 is located in the engine compartment fuse box. To access it, open the hood and locate the fuse box near the battery. The specific fuse for the power receptacle is typically labeled in the fuse diagram found on the cover of the fuse box. Always refer to the owner's manual for precise fuse location and specifications.

I know what would happen. The three amp fuse would blow. Any device that is plugged into a receptacle with out having sufficient resistance to limit the current flow will dead short the circuit and cause the breaker that feeds the circuit to trip. In this case the fuse being of a lower rating that the feed breaker the fuse will blow without tripping the receptacle's feed breaker.
AnswerThe cigarette lighter does not have a relay. It does however have a fuse. It may use the same fuse as the radio. If all fuses are good, suspect the lighter itself is bad. Try your lighter in a know good lighter receptacle. If it works there, then suspect the lighter receptacle in your car is bad.My Haynes repair manual for model years 1990 through 1993 states that the cigarette lighter relay is found in the left end of the dashboard below the PGM-FI relay.
There is no fuse in the unit itself. The fuse in the charger in in the plug.
