Hi

My parents C3 has the popular heat only blows on setting 4. I've located and taken out the resister pack and tested it, it seemed to have resistence between he pins and the fuse. I got a new themal fuse anyway and soldered that on.

Still only works on settin 4, could it be the whole resister pack that needs replacing?

Where can i get on? I've looked on ebay and they seem to be different to the one in my parents car.

You can test each of the individual resistors in the pack (off the car), by using a meter set to ohms and meter between where the white wire connected to and then each of the other 3 pins, and you should get a different resistance each time.

If its open circuit, or just one flat resistance, no matter which pins you are measuring, then the resistor pack is worth changing.
I got a new thermal fuse anyway and soldered that on.
Double check that with an ohm meter too, as it may have been tripped during the re-soldering.

This part on eBay: Heater Resistor looks like the part you have, fits petrol 1.1, 1.4 and 1.6 from year 2002.

There were quite a few different heater control parts fitted to the various years and models of Citroen C3 through the years. Some had air conditioning, some climate control, the petrols differed from the diesels and changes were made as the models progressed through the years.

Be specific with the year and model information and you can be more confident you have found the right part.
