When my car idles the radiator fan spins very slow and the temperature gauge goes up. If I turn on the air condition the fan spins faster. What could be my problem? The main fuse 120amp was blown I replaced it with a 100amps could that be the cause of my problem?

It sounds to me like you might have some unwanted resistance in the fan circuit. I have included a troubleshooting guide and a wiring diagram in the diagrams below. Please go through it and let us know what you find out.

Thanks,
Alex
