Try running it w/o the thermostat and see what happens an open thermostat will not give you enough heat to get comfortable or to cause it to overheat

You might want to make sure your heater blend door is working properly. I had the same problem and finally figured out the door was not working and had to have it replaced. The dash will have to be removed for it to be fixed. Good luck.
