Xsara Blower On Full Speed

[gergototh]

Hello everyone

 

I just bought a 2002 Xsara 1.4 P with A/C and found out the heater blower always on full. I have cold or hot air if i turn the temperature switch, but couldn't control the blower speed.

I ordered a resistor for the blower, changed it, but with that I hadn't got any luck. No blower at all. Found a few forums, youtube videos and I have different ideas:

- the ordered resistor is faulty

- need a new blower with resistor

- igniton switch??? (how to find out)

- heater control unit (as I said I have heating if I want, and  rear window heating as well)

 

Any suggestions?

 

Many thanks

Welcome to the forum.

 

Normally this would be the resistor pack. Did you get the new one from a Citroen dealer and if not is it a new one or a used one which as you suggest could be faulty ? If you have a meter you could check for different resistances across the different pins on its connector and see if it is the same as the old faulty one.

 I bought it from a top seller from ebay (new, I hope. Was £11.9)

 

What is the not normally issue? Suggestion?

If not the resistor pack then maybe it is the controller, I found these from a search:

 

 

  Fixed it at last!!!!

It was the blower fan controller. This is a unit about the size of a
cigarette packet and is found in the driver's footwell on the left, fairly
high up. Thanks to Paul at the Citroen Centre for telling me this.

Taking the unit out is awkward but not impossible. There are two sockets,
coloured green. One has a pair of thick wires (presumably power out to the
heater fan motor), the other has two thick and four thin wires, I guess that
this is power in and the vanbus multiplex control in and out. You need a 6mm
socket but I would recomment using a magnetic one in case you drop the
fixing self tappers behind the carpet.

Most of the bulk of the unit is a large aluminium heatsink There is a power
transistor inside the unit but I marmalised it trying to unsolder it. The
heatsink clearly seems to work when a soldering iron is used.

Having marmalised it, I had to buy a new unit. Much ferreting and phoning
around and I found that it is Valeo part number 509355 or Citroen part
number 6441L2.

I would recommend Neil Goodall at Vantage Citroen parts 0208 544 9997. He
keeps most Citroen bits. Cost is less than 40 squids plus the dreaded VAT.

Hope this helps all the other people who have reported thae same fault. It
is probably no more than a ten minute job to change the unit for a new one.

  Hi All, I had the same problem on the latest model of Xsara exclusive. I followed the advice of Blower post and fixed this by changing the 2 darlington pair transistors in the blower speed regulator.
 

 

There is also this which includes a warning that the pollen filter should be checked/replaced since it may cause a high load on the blower if blocked and result in the controller failing. We used to have a Xsara Picasso and the service included to replace the filter each year to prevent the ignition switch burning out. http://www.blower-motor-resistor.co.uk/citroen-zsara-heater-blower-motor-control-unit.html

Thank you so much for your time. You are a legend. I saw this post somewhere but when I search for this "cigarette packet" size blower fan controller just finding the same stuff on ebay/google. 

I  think I will change the blower. Far as I remember when I had similar issue in my gf's megane mk2, the new blower running much freely than in my Xsara.

Thanks again and I will be back, when I have the part.

 

Thanks again Paul

My daughter's '02 Xsara was running at full speed a couple of years ago.   I changed the resistor pack which cured it but within two weeks the motor stopped altogether. I got a new motor unit from ECP and it's been fine since then.

Thanks

 

I ordered today a new blower unit for £69 with warranty so fingers crossed

Hi

 

So the blower arrived on friday. Arrived in a nice box with wires as well. Changed it and it works. AC also.

 

Thanks for the help everyone

Another problem solved. Well done.
