Having problems with your Cars & Trucks ?
Greetings this is my first post here. I have a heating problem with my 2001product dodge grand caravan sport . The heater blows cold air but as i drive it will blow hot air briefly then back to cold air. I just replaced my blower motor resistor hoping for the best and it still blows cold air. My coolant res is emty but my radiator is topped no leaks and im not overheating please help me someone its cold here in NY
Glad you found the problem
Keep reserve full, green antifreeze, Clean if it is not ,flush system, shoud be done, every 25,000 miles or every 2 years,if that is empty you are loosing antifreeze somewhere? do you have rear heat? check those lines under car? the metal pipes rot out and leak. Change your Water Pump, that is what moves the system. Is the temp gauge on dash showing in the middle like it is warming up? Thermostat change. that shows antifreeze temp which goes through heater core to warm up the car. No antifreeze smell in car right? burnt maple syrup?
