    You probably have a clogged heater core. Very easy to check. With the engine at normal operating temperature and the heat on, feel the 2 hoses going into and out of the heater core through the firewall. If they are cold, your heater core is clogged. You can flush the heater core by disconnecting the hoses and connecting your water hose to one end with the other hose set to drain. Turn your water on and off repeatedly to pulse the pressure and dislodged the gunk untill the water runs clear and then reconnect the 2 hoses. Make sure you disconnect the battery before you do this and towel dry the engine before you restart it. If the hoses are hot, you should check the heater control valve for proper operation. Good luck and let us know how it goes!

    thanks for your help. im going to try it when I get home ill let you know if it works or not :) and should this help with both the over heating problem and the heater?

    Since you said it was not overheating, I ignored that part of the problem. See how it works after the flush. If the light keeps coming on, the only thing that could be wrong is the sensor that you replaced.
