Just replaced heater blower electrical connection block as it had burnt connectors and stopped working, all wired up but now blower on constantly.
Any ideas why?

Does your car have manual or automatic temperature reg?
If it's the manual panel with the dials, the fan control variable resistor itself often fails.

That's annoying Ian, I don't think my Haynes manual for the Xsara Pic has specific info about the automatic module but I will check and pass on anything in there

My Haynes manual does not cover it, only the old style manual knob

Could be a failed resistor pack. As an aside, have you been keeping up to date replacing the cabin filter, a long time ago I read that the ignition switches can burn out if the filter is not replaced.

Replaced resistor a couple of years ago, to be fair not sure when I Replaced cabin filter but probably last year when I serviced it.
It's my daughters car and I don't keep a record of what I have done and when just glad to give it back 🤣 I am a volvo man and I hate her car but I do want I can to help her.
