Where can i find fuse box as heating not working for volvo s40

Have the climate system scanned for fault codes. This willpoint you in the right direction. Need a shop with the Volvo Vida system

The problem is either a vacuum line or a bad motor controling pass side air box

cheeck heater fuse

i would ask the experts on brickboard.com they have a specific section for every volvo made

yep could be, but check both radiator hoses if hot to touch problem could be heater water shut off valve, problem could be in the heater ac control module or heater air door or flap door actuator could be faulty many things will cause no heat problem but check to see if thermostat okay that could be the problem also check engine coolant level make sure there plenty coolant in coolant system.

Check the coolant in the radiator or resevoir. it's probably low

The drain on the evaporator is stopped up,look for it directly bellow the ac lines ,where they go into the car,under the hood,it will be on the bottom of the blower box,use air pressure to blow into the drain to clear it out.

hi i have a 98 s40 and and even though the blowers all work it does not blow hot air any ideas?

check fuse, maybe you just have a blown fuse. Or you might want to see if you need it charged.
