i have a 2000 honda civic ex and all of a sudden the heater stoped working. i have checked all the fuses and none of them are bad. i even replaced them to see if it worked and it didnt. i dont know what else could be wrong the heater was working fine and then it just stoped and the lights that control the a/c, recirculate, and rear defog dont work either. i dont know what is wrong but hope it is something simpil.
