Xsara Blower/heater

[redbuller]

Hi all, does anyone have advice on fixing the blower/heater in a `98 td xsara...I have the car about six months and it worked ok but only on the higher settings but now its stopped altogether. I was reading a post which suggested it could be a resister and that it was an easy fix. Anyone have any advice on how to check if this is the problem and where its located. Other than that its a cracking wee car i love it..

 

 

thanks all

if it was only working on high speed it will have been the resistor. if its gone off altogether now it might be the resistor has gone down altogether or a diffrent fault. try a resistor first as you needed one anyway and go from there. when you go for part ask dealer for wiring diagram (the three sheet one) and one of the sheets will have a picture of the car showing where all the components are located.

cheers thanks for the reply..i`ve found out where its located so i`m going to have a look at it first...then next stop will be the dealer...thanks for the advice on the diagram though i`ll get one when im there.

Just a quick note, when I got a new resistr from Citroen i kept the old one.

With the help of Maplins i managed to get a replacement thermal resistor (only cost 47p) I then took the old one off writing down the layout (all the connections are pressed and not soldered). Once i did this I tested it out and it works fine, I now have a spare. Talking to the dealership they said that this is a common fault on the range, so i think as long as this works it cheaper than citroen.

was it hard to do? i have the same problem. where are the resistors located?

Not hard at all, the only problem came when trying to read the thermal resistors rating, but the local maplins did all right.

The unit is behind the glove box, the screws are under the trim fabric, the unit just turns to the left if memory serves correct and pullss out the rest is self explanitry,

best of luck

Hi all, I seem to have the same issue now on my Xsara - can anyonce confirm where the resistor lives and what the part number is that I need to order from Citroen?

 

TIA,

Hi i have the same problem have managed to remove fan but don't know which part to replace did you ever find out. Is it a transistor or resistor.

thanks

Just out of interest, the Maplins part # for the termal cut-out is RA18U....it's also available from Farnell part #476602.

Not too sure how to re-crimp the lead connections though as they don't seem to want to open...may need to solder it, the metal tabs seem to take solder OK

Can someone clarify which part we are talking about please, I have just developed the same fault (only works on 4)

 

Is it the round plastic thing mounted in the heater pipe? with four wires going in and number of silver coiled bits of wire on the other side, i.e. in the pipe?

If so what do you replace if you are doing it yourself? Presumably you get the whole thing if you buy it from citroen, can you replace the individual bits from maplins?

Hi I have a xsara with air con heater fan full on, i have bought the maplin thermal fuse and I have stripped out the fan motor, I cannot find out what part I have to replace to cure the problem. can anyone give me precise instructions on which part and where it is situated?

[Typhon]

If your blower don't work at all, it may be the relay for this circuit. It is located beneath the fusebox and is an easy switch.

 

However, my fan suddenly began to blow at full speed and i cannot shut it off :unsure: will it help to replace the resistor?

Mine has too, I have bought the maplin part, removed the fan, removed the fan from the housing underneath is something called on Ebay a Reostat, it is an aluminim casting, with a coil, and and appear to be riveted together .. there is one resistor I can see on the top yellow .. but running a volt meter across that appears to still have continuity ..

is the resistor in here I am supposed to change or am I totally wrong ?

 

here is the resistor image as from maplins

[Guest bradford]

Okay ... I couldn't find out which components to change either, and couldn't find anything on what to check .. so bought a new Rheostat (advertised on ebay) .. app it is the same one for the Berlingo and other Citreon vehicles..

 

before installing I checked the resistnace across the contacts and got these .. not sure if it is any good to anyone .. but it might come in and save someone some brass...

as I said - I have nothing to benefit from this, and this is on goodwill without any warranties or come back on me, just simple readings - incase any "hava go's" out there wanna dabble with an iron before shelling out £60 on a new part ...

 

there is another good post on here too, which helped me out greatly .. pay paritcular attention Xsara people to the note from Ian Collins on the pollen filter .. mine was black and I must have blown a good egg cup full of dust out of it with my airline (as a temp measure) - I will bid on a new one on ebay as they only seem to be going for around £5 ..

thanks for a smashing forum !! top class ...

The heater fan on my Xsara has only worked internmittently for a while and now has stopped altogether. It sounds like the relay to me so could you be more specific about what you mean by underneath the fuse box. Under the fuse box there apear to be three small 'boxes' tow green and one yellow, that look as if they could well be relays. Is this the right location and if so which one is the heater fan relay Thanks for any help given!

[techbod]

the relay plate is above the main fuses and there are places for 13 depending on what the car has this is how they are laid out and relay 5 is the blower,

 

12-13-------------1-2-3-4

--------------------5-6-7-8

-------9-10.

 

 

the resistor from maplin is the right one but doesn't belong in the part above its on a plate on the blower housing held in by one screw ( snip the resistor out and don't solder the new resistor in because it will blow it instantly because of the heat ) you need to crimp the ends to get a good connection.

 

rough idea where it is

this one shows where the resistor is atached

Be carefull if you solder it in as it it a fuse which blows when it gets above a certain temp, it has a very soft metal inside (thats why it is crimped). :lol: It is designed to cut the power if the resistors get a bit too hot (ie if the fan seizes up). The heat of the soldering iron can make it pop! ;)

[techbod]

crimp it with pliers but the proper tool is a flash spot welder which does not distribute heat along the wire and maplin also sell them, as I said ( do not solder it ) :lol:,

 

to crimp the ends bend them round the wires at the end the compress them together with the pliers
