ok here is the story i have 98 accord with 54K on it and it's a 4cyl auto. this car was overheating about a month ago when it was just parked when driving the temp stayd noraml.i noticed my fans coming on too late. so i took it to the shop and they said it was the thermostat and they changed it with i guess one they got from napa (i don't know if it matters). so today i was running my car in my grage cuz i was on the phone and i noticed the two more lines that arrow was about to hit the (H) so i kept running the car but my fans were not comming on, so i turned on my heater full blast.it moved it 2 lines down but still my fans were not comming on. so i decided to turn the AC this way both fans came on when the compressor came on and i shut off the ac after 5 seconds and i noticed that my fans stayed on. now i don't know what the helll is wrong. (did i trigger the fans to come on by turning on the AC?). can i somone tell me what to do please cuz i'm about the sell this car.
