Do not try this at home. For HVAC professional use only. This video shows yours truly changing a blower motor ...

under dash but first check fuses ,switch and relay. Big job to pull the heater out from under dash.

Its located under dash,or near glove box.

The dash panel lower side has to be out.

HEATER BLOWER MOTOR

Its faulty blower motor resistor. The low and medium speed on blower motor is controlled by resistor and its actual speed is high. So because resistor is not working, blower motors actual speed which is high is working.

It can be faulty blower motor or faulty blower motor resistor. Get the blower motor inspected. If it's faulty it has to be replaced.

These will help.

Thanks.

Before you rip, check the 30A HEATER CIRCUIT BREAKER in the instrument panel fuse panel. The input is hot with the engine running. CB output connects directly to the heater blower motor. A cluster of heater blower motor resistors determines blower speed as selected by the blower switch in the heater control assembly. The switch setting is sent to the powertrain control module (PCM) which acts to turn the blower motor on at the selected speed.

You have a defective heater blower resistor, the part is located next to the blower motor in the air ducting that it uses to cool the resistor.

Before removing the heater switch on this 2006 citroen hdi I would first have the blower motor checked and the most common reason for this and other blower problems would be the blower resistor.

Your blower works on and off at times, first locate the blower motor and the resistor. the blower motor is located on the heater box, look under the pass/side of the dash, you may have to remove under dash cover to see blower.
When you have located the blower now look to the side on the heater box, there you will see a connector plug, it plugs into a connection on the heater box, this will be the resistor, the resistor slides into heater box and the end of it bolts to box to hold it in place and then the connector plugs into it, if you can not locate it then follow wires that plug into blower , follow wires back they will lead you to resistor,
next time blower does not work wiggle connector to resistor and see if blower turns on, if it does then resistor is the problem. also unplug resistor plug at resistor and check for any burning of connectors at plug and inside resistor.

I would bet its a bad resistor or the plug is brunt due to high draw from bad connections, if plug has burn damage to connectors then replace the plug along with resistor.

The blower motor is located on the passenger side of the vehicle next to the blower motor. Run the fan on high and listen for the blower motor location if in question. The resistor will be mounted into the heater case and held in by two screws.
Good Luck

look in passenger foot well on blower case for 4 wire connector.

resister bad would still allow high speed. may be blower motor.
