Probably pinched vaccume line or improper alignment of device that vaccume lines are connected to! also could have clogged heater water line.

SOURCE: 2000 kia sportage new heater core no heat

You most likely have air in the cooling system.You would need to bleed the cooling system of air.There should have bleed screws near water neck,or thermostat.Do this cold.Remove the radiator cap and fill full.Then start the engine and loosen the screws and watch for nothing but coolant to flow out(no air or bubbles).When you are sure the air is gone out of the cooling system,shut the bleeder screw off,and fill radiator up and test to see that engine runs cool,and you have heat at all speeds and rpm s.The electric cooling fan should come on at a tempuratue of about 215 or so.But just as important,the cooling fan should cut off at a lower tempurature.If the cooling fan does not do this,you still have air in the system.If you can not get the air out this way,then do this.Remove the radiator cap and reservoir cap and fill them both up full.The reservoir needs to be over the fill mark a good deal.Replace the caps.Start the engine with ac and heat off.Let it run until the engine gets to about 212 or 215 degrees and shut the engine off.Wait about 30 minutes and check the reservoir to see if the coolant has dropped.It should have dropped.If the reservoir has dropped or not ,do this again and again untill the reservoir drops in coolant level,and engine temp is good(fan goes on and goes off).Remember to refill the reservoir as needed as it drops,not to run out of coolant.

SOURCE: no heat and have had the air cabin filter

I'm going to go out on a limb and say it could be the blend door. This is a door that switches air from the A/C side of things to the heat side of things. Also if you are leaking coolant it could be the problem but I would check out the blend door and make sure that it's working correctly. Good luck and feel free to ask more question!

SOURCE: replaced thermostat and flushed out heater core 3

If the heater core is not damaged or leaking ie: if you don't see coolant on the INSIDE of your windshield or coolant on the floor inside the car then chances are you may just need to BLEED the radiator.

remove radiator cap

Fill coolant resovoir to the cold line if the engine is cold from sitting overnight.

Start engine with cap off

Wait till engine gets hot

While waiting you will see a big gurgle of air bubbles come out and the coolant level will drop

Fill the radiator with more coolant to compensate.

When the fans come on and it stops gurgling air install the radiator cap

You are done

Watch the coolant level for the next few days and top off in the resovoir as needed to keep it filled.

Your heat should be very hot now providing you installed the correct oem thermostat correctly.

Hope this helps

No heat.. replaced thermostat, radiator, water pump, heater core is not blocked help

Under the dash on the passenger's side, right next to the fan (to the left of it) you'll see a plug with 4 wires (green, blue brown, and black with a pinkish tracer) unplug it and remove the 2 screws/bolts (7 mm I think.) Pull out the temp relay (not actual name but it escapes me right now). And Viola, there's your problem. If I've helped please rate my assistance and leave a testimonial. Happy Holidays!

No heat

Sounds like the radiator line are plugged. What you can try is taking off one rad hose lin 1 Side at radiator and the other at the water pump to engine Run water through lines leaving both lines open should flush all debris away may have to do it a few times. Where this runs thorugh heater core and back out. But do not use alot of presure from the hose.

96 Jeep Country-Heater blowing warm; NOT hot

unless you got visable signs of leakage its not heater core, but it could be pluged with sediment. take off both heater hoses and flush it both ways until it runs clear. you can also mix a little baking soda and water and pour in core and let set for a while and then flush.
