Thermo Fan Questions!

[Keesh]

last night after singling it up my car over heated.. i was wating for the thermo to kick in and nothing! i was given the over heating beep for the first time! naturally the first thing i did was put the air con on full blast(which is also stuffed atm) and the thermo fan didnt come on.. what are the usual problems that cause this? im going to do a diagnostic to see if it comes on then.. are there any fuses under the hood that i should have a look at?
