Heater controls - advice on new part required

[mhjc]

The heater on my 2009 XTR 1.6 diesel is only working on setting number 4 - it's basically all or nothing!  

I have been told that this is caused by the resistors failing but wondered if anyone could advise me on the specific part I need to buy and how to fit it.  One thread I've found seemed to suggest it was a plug and fit part, another suggestion seemed more complex and involved soldering in new resistors...

Car is currently in France so I want to make sure I have the correct part when I go over next week and would prefer an easy fit rather than a soldering job if that's possible.

Any advice much appreciated.

This is probably the bit you need,

I've not replaced one, so can't tell you how to do it, but I would think it would be covered in the Haynes manual.

This is becoming a common hiccup with the B9. Straightforward swap. Proceed as follows:

Remove the panel below the steering wheel that curves under the dash. Three pop and several spring clips (small screwdriver on the pop clips).

Acting like a monkey with a torch, you'll see the heater motor above the accelerator pedal - it's held by four 5mm screws. Don't remove it - I mention it just because it helps locate the part you need.

From the motor, follow the plastic heater duct, and towards the left rear of the motor you'll see a single 5mm screw, holding a small rectangle of plastic. This is the culprit you need to change, and it sits in the heater duct.

Remove the screw, slide the fitting back about half a centimetre, and the resistor pack will come loose. Unclip the electrical plug and the resistor pack will be free.

Reverse the process to fit a new resistor assembly. You can test it briefly before fitting it by plugging it in - but be brief, because it needs airflow to keep it cool and it gets very hot very quickly!

Ebay, around £25 - as the link above.

I recall reading of the resistor packs constantly failing on a different vehicle, it was down to the thermal fuse blowing.
The solution was to replace the thermal fuse with a slightly higher rated version.

You can't solder the new fuse in place as the temperature of soldering will blow it so you have to devise a way of attaching the new fuse.


In the picture below a terminal strip connector has been used, it has been stripped of the plastic covering and cut in half and a piece used at each end to secure the new fuse.

As jj9.
I have pulled this trick and it works, depending what's wrong with the resistor assembly. Cheaper than buying the complete resistor pack, but a pain in the butt if it doesn't work.

There is a guy on the Bay who often advertises thermal fuses for resistor packs. He charges around £5 for one. Maplins will sell you dozens for the same price!

Many thanks for this - really helpful - such a great forum!

[mhjc]

Many thanks for all the advice. I'll post how I get on in France!

Was it something with the fan speed control that caused all those fires in the Vauxhall Zafira?

[Satellitemark]

Very likely , on my Vauxhall vivaro (Renault's trafic in drag) I had a small fire on the bulk head where the sound deadening caught fire. Around the resistor pack, I caught it quickly and put it out with the help of the guy who's house I had to stop outside I soaked it with his watering can and tore the material away to prevent further ignition. I have a new resistor pack but haven't got round to fitting it yet.

Thanks for the info, he helped me to replace it while in the Citroen's motherland.

It didn't work for me although with some twiddling of the dial it either works on full-blast or the lowest setting (regardless of what number you choose). At least I can rule out the resistor pack being the root of the problem.
