Peugeot 406 blower fan not working

00 2.0 HDI Climate control blower stopped working - 406airconproblem
406 estate X Reg 2.0 HDI Diesel.

Aircon on climate control not cooling for sometime , probably due to loss of gas over a period, not bothered about this.

However Interior heater / cooling blower fan has now stopped working alltogether.

Checked fuses F2 & F40.

Checked blower motor works with a direct feed.

Checked feed OK to both fuses above from ignition switch.

So from haynes manual wiring diagram , fault can therefore now lie in either :

Blower control module
Heater Panel
Air Thermistor

Any thoughts on whats next best course of action to trace fault, am I missing something obvious to check before trying to source say a new heater panel ?

Would the aircon pressure switch turn off the blower ? Thought this would just stop the aircon compressor turning on ?

Any advice welcome ?

Sounds like the electronic fanspeed regulator has failed.It is situated in the air ducting adjacent to the blower motor.If I recall it has a green multiplug electrical connector attached to it.The a/c inoperative will not affect the operation of the blower motor function.hth

could be resistor for the fan but may also be ignition switch as am sure feed for fan runs from it.

sorry about the round about way of going.My blower is not running also,but when it stopped working a 40amp fuse in the engine bay was blown.Since replacing it my car will not start dash says engine immobiliser fault.ecu,bsi,ingnition transponder have all been change key is still matched to bsi.Also high and low pressure pumps have been changed camshaft sensor checked and ok crankshaft sensor changed and still it will not start HELP PLEASE
