you will start at the blower motor itself, hotwire it with power and ground, if that works then work your way backwards in the system, the blower resister is usually next in line and a big problem on many cars. Looking for burned connectors, broken resisters and then tapping on the main control unit and wiggle the wires connected to it may find the problem, if your blower is intermittant, it probably is not a bad fuse but could be a weak connection, a volt meter will do a lot of the troubleshooting for you once you get access to the connectors, lots of information on youtube.
