I own a 2004 Chrysler Crossfire and this weekend I noticed the low Coolant Light flashing and it turns on and off every once and awhile. It doesn't turn on right when I start the car only when Temp guage shows about half or barely above the middle tick. then I also tried to turn on the air and the fan motor is making a weird noise that is consistent with how fast it's spinning. Any help with what the actual problem could be and or how to troubleshoot
