I've looked every where, but couldn't get one straight answer through the internet or any other previous NICO topics. My car was overheating which i found was the problem due to a bad thermostat which i changed and the car ran great had heat and all that... WELL then 2 weeks later a heater hose broke and I lost heat. I fixed the hose and refilled the coolant/water mix. I had heat for another day then it stopped working again. No holes in any lines and coolant is full and car is not overheating. Car has been running fine and it seems the only problem is my heat!!

please help!

I would completely flush the entire cooling system out and start over again. Sounds like there's air in the system if it's like an intermittent problem. If that doesn't solve it, maybe replace the heater core?

You've got an air bubble in the cooling system. It'll work out eventually, or you can drain the system and fill it again. Make sure you keep the HVAC control at full hot.
