Here is how to change a blower motor resistor in a Citroen relay. You can tell it’s the relay if you start losing blower settings. For example your van heating will only work on settings 3 and 4 but not 1 or 2. Strangely for us ours didn’t work after we changed the resistor at first. We took it for a short spin and it started working and has worked since. Really not sure why that was hopefully someone can tell me. Normally it should work straight off. Haven’t a clue why I needed to drive first for it to kick in.
