You might need a better thermostat,also make sure your antifreeze is up to par,get a cheap antifreeze tester to check it,but do this when the car is cold and has been sitting for awhile so you dont get burnt

    I tested my coolant and it is great. Still just barely warm air for heat and defrost.

SOURCE: heater core replacement

This is a really easy job, disconnect the heater hoses at the firewall, go inside the truck on the passenger side there is a plastic panel/cover over the core, 6 bolts/screws I think, remove the cover pull the core, tops 1 hour, as job at work I did them in 20 minutes.

Inside the venting is a flap that is controlled by a vacuum operated actuator. This vacuu hose also runs to your control panel.. Either the vent is stuck, the actuator is faulty, or there is a bad/leaky vacuum hose

SOURCE: 2002 explorer a/c blowing out of defrost and not dash vents

The direction of the air flow (dash/defrost/floor, etc) is controlled by vacuum going to the switch. There may be a vac line that didn't get connected or was damaged when they put the replacement engine in it. Check the lines on the firewall to make sure nothing is loose.

No heat engine warm fan works on all levels directional control (defrost@floor) stuck on cold. ?temp control .


your heater core could be plugged if your anti-freeze color is a brownish colour , most likely your heater core is plugged also when you move the direction for heat control can you hear the blendoor move if you can then again your heater core may be plugged and if it is plugged flushing most likely wont fix it, if you don't hear the blendoor motor move the blendoor motor or the door may be damaged

No interior heat in my 2000 daewoo nubira


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 cnc_couple@live.com

Heater stopped blowing in all settings, except defrost.


Here's a link that may shine some light on it for you. I'd probably try to get to the spot where electrical connections are first, and try removing it, cleaning all contacts etc, & re-try.
