Now when I went to start the car everything started fine car was running like 10 mins the heat never got warm then it shut off red exclamation popped. I turned off an on then I heard a humming kinda soundig pitch coming from front of car that gott higher and higher then shut the car off and red triangle pops up and that's what it's doin now. Please help
