Default Heater is not working

I check the manual for fuses and I didn't find one that dedicated to the heater, any tips on which fuse it might be or what i might do?

First of all, welcome to the forum. As to what you might do, you might give us a lot more informatuin. Like, does it blow air? Think about your question. It is like calling the doctor and saying , "My stomach hurts, what's wrong?"

Engien bay fuses 1 and 15, trunk fuse 15, and probably others, supply climate control power.

lol, good one sparkenzap! and yea i agree with you, we need more information to properly diagnose, if its not blowing at all then i would check the fuses spark recommended. But if its blowing and it doesnt get hot then i would first check my coolant level to make sure theres enuff antifreeze. Antifreeze circulates through the engine block and heats up as the car gets warm, then when you turn your heat on it is transferred from the block to a small radiator like device in your dash. Air is blown through the radiator containing the hot liquid and presto! you have hot air coming out, however if there isnt enuff antifreeze or none at all then the car wont have enuff to cycle it through and the air will blow out cold. If you have enuff antifreeze then it may be something else, like your thermostat.

Soooooooo, if you want a list of things that could go wrong, here is some of it. Clogged heater core. Blowers inop. Bad control module. Bad control panel. Chaffed wire. Circulator pump not working. Thermostat stuck open. Clogged heater hoses. Stuck water valve. Flaps not working. Just to name a few.

Definetly go with what black said but id start with the coolant levels first if your blower and everything else seems functional. i usually start with the easy stuff before i go pulling things apart and causing problems i didnt have at the start! Good Luck, these cars a relationship so the more involved you are with her the better she will treat you and the better you will treat her!
