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

2003 mercury sable blows cool air when heater is turned on.

Most likely it is a clogged heater core. Have your heater core reverse flushed or your blend door is stuck open.

My truck wont blow out any hot air, just cold. i put a new radiator and thermostat in it. it is full of anti freeze

Try removing the Heater hoses from heater tubes(be careful not to break heater tubes off) then back flush heater core with garden hose(Don't use a lot of pressure). Jell from antifreeze builds up in the heater core and blocks the coolant flow. If it is easier, remove the heater hoses from the engine, that is safer. Back flush the heater from the hoses. To Back Flush (The hose coming from the water pump is the inlet)(Hose going to Manifold is outlet) Back flush outlet hose! To much water pressure may cause damage to heater core!!!! Do Not ues AIR!!!!

Replaced thermostat on 1984 300zx non turbo. no water leaking any where. still getting hot, only small bubbles in resivoir tank. top hoses very hot. lower hose not hot any suggestions?

you may have air trapped in the system, or there may be a blockage somewhere. usually, a blockage would be in the heater core. to check, remove both heater hoses going into the heater core and try to flush it out with a garden hose. it's also possible that the water pump is faulty.

I put stop leak in radiator and now the car blows cold air vs hot air when running the heater. why?

The stop leak have restricted the coolant flow to your heater core. You can try flushing out the Stop leak with Preston Radiator flush or replace the heater core. Once Cooling system flushed out, replace thermostat, radiator cap and repair coolant leak. Good luck and hope this helps, and Note: Common Black kitchen Pepper does great as a radiator stop leak without leaving any residue and can be cleaned out of the system with water and not coolant flush. Two table spoon is more then enough to stop a small leak. Good luck and keep me posted friend.

2000 Xterra intermentantly overheats (temp gauge goes up) no leak appears present. Coolant level appears correct. Heater will blow cool air, then start blowing hot air. Temp will then come back to normal....

sounds more like the thermostat may be failing. generally a water pump starts leaking out of the "weep" hole in the casting before it quits. just look at the front of the water pump for a greenish streak or an obvious leak.
if you also suspect you heater core may be getting plugged now would be a good time to back flush it to get rid of some of the gunk.
