I am having a problem with the heating. The car has heat when the car is in motion, but when i am at a stop sign, or light or park cool air comes out even after the car has been warmed up. The car runs fine.... besides 1 oxygen sensor needs to be changed. The heat works all other times only when the car is not in motion any ideas? thanks

Check the coolant level. If that is good, then you probably need a thermostat and/or water pump.

u need 2 check your battery recharger pack, because it is probably not keeping the energy from your driving and transferring it into the battery right. can you turn on a light while stopped? it might also be that the cable from the heater to your battery is bad, but from the direct battery the engine produces is still intact. Just a thought...
