so I went out to start the crossfire this morning & I hear the fan motor kick on ? never did that before so I continue to turn the key & nothing ! All the gauges come on & light up but no cranking Acts like a dead battery ? so I check the volts on battery ok at 12.4 Car has been in storage with charger on . I have moved the car just a couple of times out of garage this summer for pool supplies with no problems ! I did hear like a crazy cricket sound a couple of times while I was in garage earlier this month never did figure out why it was doing that ! 1st cant figure out why electric fan would come on & second why it acts like its got a dead battery went it not ? anyone ???
