Remove the radio. Daewoo printed the code on a sticker on the top of the radio on some models.

3 possible issues here,

the first is that your thermostat is stuck open, when this happens the air will barely be warm, luke warm at best, replacing the thermostat will fix this problem

the second, is that you have low coolant levels, when your coolant levels are way low, your heater core doesn't get the proper amount of coolant (if any) and the system blows cold air instead of heated air.

The third and final possibility, is that your heater core has clogged up (usually happens when stop leak or some type of radiator sealant is used) when this happens you can feel warm air when accelerating (test this by gently reving the vehicle and holding the rpm's when it is in park and holding your hands over the defrost vent to check for heat.

If you can tell me what symptom your vehicle is having I can help with instruction on how to fix it thanks [email protected]

You can disconnect both hoses and blow compressed air through the one that stays cold, this should free it up then recommend a coolant flush.

on the front under timing belt cover ,back cam ,if its not their then back of head about 3inches along from the gear wheel end

first you need to remove the belt . there are only several bolts to remove the alternator . there should be a diagram on the panel by the hood prop rod to show the belt route

it is the heater core it is located behind the dash im a certified mechanic and have replaced many of these

best advice take it to garage they are not a diy recomended job
