When is the fan supposed to turn on? If I start the car up cold it should turn on before the car even warms up right? I let my car run for 10 minutes and the fan never kicked on. Could this be the resistor?
If you are talking about the cobra, no. The fan only turns on when the A/C is on or when the car reaches a preset ON temp in the pcm at which the thermostat is already open and allowing coolant to flow, but not allowing the car to overheat or run too cold from fan turning on too late or early.
