Air blower not working - 2004 Peugeot 307 SW

check and test fuses -relays for a/c system

There are several possible reasons why your blower, vent, defrost, AC, and heater might stop blowing air:

1. Blower Motor Failure: The blower motor is responsible for blowing the air through the vents. If the blower motor fails, you will not get any airflow from the vents.
2. Blower Motor Resistor Failure: The blower motor resistor controls the speed of the blower motor. If the resistor fails, the blower motor may stop working or only work at one speed.
3. Fuse or Relay Failure: A blown fuse or faulty relay in the blower motor circuit can prevent the blower motor from working.
4. Control Module Failure: The HVAC (heating, ventilation, and air conditioning) control module is responsible for controlling the blower motor and other components. If the control module fails, it can prevent the blower motor from working.
5. Vacuum Leak: If your vehicle uses a vacuum system to control the vents, a vacuum leak can prevent the system from working properly.
6. Broken Blend Door: The blend door controls the direction of the airflow. If the blend door breaks or gets stuck, the air may not flow through the correct vents.
7. Wiring or Connector Issues: Faulty wiring or connectors in the blower motor circuit can prevent the blower motor from working.

a Volvo (must we guess"?) 2010 xc 60???? no air jumper-ed too?
if yes controls bad.
but with all blend door motors dead, air will flow.
there is no blower blocking door/damper ( but Filter)?
no air flows? means what?
hot air?
cold air?
either?
or no ambient air flows. or all.above.?

most cars have at least 3 dampers
MODE (direction)
hot cold, manual control.
recir'/fresh.

case in point, if hot core and AC core are dead
and blower spins you still get ambient cab air flow or fresh.
cab filter clogged up.
I need more facts to know what tests to do.

Have you checked the blower fuse?

Just because the Blower works doesn't mean you will get air delivery. If the Blower is working but the Blower FAN is not spinning you will get no air delivery. Check out this video to learn more about the blower unit. https://www.youtube.com/watch?v=VpYX663B7Mc

Not sure which fan you mean. Engine cooling fan is different from heat/air blower fan.

The car normally blows air through the blower however the controls and settings of the speed of the blower are controlled by the blower motor resistor. The resistor controls the speed of the blower fan. If your blower still works on the highest setting then the blower itself is still in working order. If you are not getting any air at all, even on the highest setting, then chances are the blower has gone bad, blown fuse or open wire. If this does not help please give us more information to work with.

It can come and go. It sounds like the blower might be bad.

Fuse ? Did you check you get power to the blower ?? If yes the blower is at fault or a bad ground.

No it can not.
You have a couple of actuators that have gone out. The driver temp control. And the air inlet actuator.
And I don't fallow your statment of "my a/c blower went completely out. I tested the blower and it works fine".

If the blower went out, then what do you mean it works fine? Are you talking about air delivery or it just quits blowing all together?
