90 defender 200 tdi heater

Hi all, my heater has just packed in it blew a fuse then stopped, im thinking it could be the resister rivited to the inside of the heater box? any more sugestions? can i buy this part or shall i buy a sheepskin coat?

Sheepskin coat im afraid as it sounds as though your motor could have siezed due to fan unit fillin with water, double check your switch aswell though.
If you end up needin to replace your blower box its not a greatly stressfull job (did mine in bout an hour or so) but drill a small hole in the bottom of the fan unit to let water out! Just another small brittish design flaw
