hi peter
thanks for that i did,nt mention on my last write up that i did try with the brown wire disconnected and it still spins at full speed so it does look like the transistor pack is to blame from what you just said but owing to the fact ive cracked the fan in getting out and putting back the transistor pack looks like im going to need a replacment blower motor anyway but one thats guaranteed to work ok it doesn,t look like you can replace the fan as it looks moulded to the motor shaft and ive located one just need to go and get it.
what do you think or is there any way i can salvage my own.

Sounds like a secondhand one would be your best bet. There should be plenty of them about - if you can find a working one! I have managed to get a couple of them for XMs and there getting like hens teeth. If you connect a battery to one and connect the pin with the brown wire to the + connection (red lead) it should run flat out. It sounds from your description to be the same as the XM one.

The buzzing sound is more than likely the small fan operating for the internal temperature sensor behind the alarm led.

M'mm sounds very strange. The only thing I can suggest is replacing the motor and control panel from the car that you know they work in, there is nothing else in the system. I cant see that anything on the car could damage the motor except possibly having a full 12v on the control lead (brown) this would be switching the transistors hard on (max speed) but I would have thought they could stand that.

hi peter
well ive had a chat with a citroen specilist and he said theres a black box under the ign switch that could couse this problem he said he,s seen the problem before and it turned out to be that
what do you think.

hi pete
the scrappy who tried the blower motor on mine said he,s going to try that motor back in the original car on monday if it works in that then ill buy that motor then investigate the problem further but another thing i could try is contact the previous owner and ask him what was happening and why he cut the plugs off in the first place his words when i brought the car was (replace the switch and the aircon will work!?).

This is a problem I have never come across before, as far as I know all the control system is in the temp control panel, behind the heater controls, or the motor, I could be wrong of course. Contacting the previous owner sounds like a good idea, he may be able to throw some light on it.
