Electric fan keeps cycling on and off. Stays on about a sec and off about a sec. Checked the fan motor, it runs when connected directly to battery. It was working fine 3 weeks ago. Maybe bad relay or controller. Supposed to turn on @ 185 and off @ 170. Also I have the probe in the radiator. Any ideas would be appreciated.
