I have a 1986 corvette with cooling fan issues. The main fan located is not coming on but auxiliary fan is. The auxiliary fan comes on at 235 degrees and with my scanner hooked up, can monitor the ECT readings. The scanner readings are 218 degrees but the main fan isn’t coming on.
The dash readings and the scanner readings are off. What temperature does the main fan come on? I checked the fan relay and the fan comes on when tested.
