Hi, i have owned this car from new so there has been no boggers been at it.

Suddenly today the heater blower stopped working on all speeds. Everything else electrical seems to be ok. I am an electronic/electrical engineer so well versed in fault finding with a meter, however, at this moment in time I do not have a circuit or manual and would be greatful if someone has had experience with this problem before. I'm guessing there will be a fuse and also a relay??? i have no idea where these would be located???
