Defender heater

Hi

I’m new to the site.
My td5 heater works on all settings but the final click downwards on the switch producing full heat/cool air has now stopped. Any suggestions?
Also main lights don’t switch off when I turn the switch off. They only go off when I turn the ignition off. Any help please.
