E36 Climate Control cuts when electric radiator fan starts

My Climate Control display and fan lose all power when the electric radiator fan starts.

The electric radiator fan seems to be starting randomly, even when the engine is cold before starting.

I have reseated fuses and checked relays. No luck.

Any ideas please?
