My fan wasn't coming on, so I replaced the thermosensor. Still haven't heard the fan come on (except for about 1 second when starting the car, and full-time when unplugging the green connector near the fan relay). I tested the old thermosensor resistance when cold (2,500 ohms) and hot (250 ohms), but never tested the new thermosensor. Does anybody know if these values are correct ? I tested my fan relay by placing an adjustable resistor (pot) in series with it and a 12.63 volt battery. I found that the relay wouldn't trip until the resistor was 55 ohms or less, corresponding to 230 mA or more of current. Since the old thermosensor never got that low in resistance, that might explain why the fan didn't come on. Does anybody know if my relay is within spec ? Thanks for any input.
