I've been using my AC a lot since I put my 280 on the road and as far as I know my electric cooling fan has not activated yet. I was parked with the AC on and temp got up to 100 and stopped but the fan still didn't turn on. Does anyone know when it is supposed to turn on. I checked the relay and fuses and all are good. I'm just looking for when it should be on so I know if something is wrong. Thanks
