Are you running a relay? If so, make sure you have good power, ground, and trigger power... It's either a wiring problem or the fan is toast.

I had the same problem with my fan install. The motor heated up and the fan never turned on. I hooked up the manual switch and was able to turn it on that way, and yes you should be able to turn the fan on without turning the car on. Of course this all depends on where you get your power from. If it is from your fuse box you can wire it to run manually or to come on only with the ignition.

Having the fan run with the car off depends on where you pull power from.
Get a cheap test light or even better a meter for troubleshooting. What kind of fan. My taurus fan has three leads coming off. 2 are hot and 1 is ground.
An easy check would be to bypass everything and just run a jumper direct from batt.
