If you're talking about the heater blower inside the car, high speed out but others are fine, it's either the resistor for that speed or the dashboard switch.

I mean radiator fan, This fan is only working on slow-speed high speed not working?


It's most likely a relay. Might be the cooling fan temperature switch; there might be two. Relays are easy to check. find the relay and replace it; you can even replace it temporarily with another one with the same rating in the fuse box just to see if this works. Getting to the switch/s is more difficult and you should have a good manual specific to your car for this.
