Question about Volvo S80
Which fan motor do you want to repair, the one inside the car for climate control or outside for engine cooling next to radiator? Inside locate fan please note some libraries have repair manuals that you can check with them for free you usually can go and find at least the location this way. Check fuse location and electrically check BOTH SIDES of the fuse with a digital volt meter not a test light some circuits in newer computer control vehicles can be damaged by test lights. Once you find the fan (inside) it also has a resister pack usually somewhere on the a/c heater assembly, check for voltage at the input of the motor AND the ground side also remember electricity needs a complete circuit.
If outside cooling motor look for a fuse box outside in the engine compartment and check that also inspect the wiring connections in line for melting usually at the motor this is a tell tale sign that the motor is using too much current. Also there needs to be a temperature switch in the cooling system sometimes in the radiator or in the engine/block/head. watch the color code of the wire from motor trace back usually to a relay or two speed resister block. Also some cars have a secondary fan for the A/C condenser I assume you don't mean this one.
