There are a few things besides fuses and relays that could fail to cause the fan not to come on. In my integra it was the coolant temperature switch. Pretty much sends a signal to the fan i guess when the temperature reaches a certain point. Check and make sure all the wires are hooked up. A buddy of mine had a POS ford probe taht the fan never came on. He just ran a switch into the cab, and when it gets about 1/2 flips a switch to manually turn the fan on.
