You might want to check your antifreeze if it's low it will blow cold air.
And maybe you should replace your thermostat as well.
Both of these solutions should make it work better.
Good Luck!

98 ford ranger no heat have changed thermostat water pump heater control valve


Maybe the heater core is plugged or you haven't bled it properly?
If the heater hose returning from the core to the water pump is NOT hot, while the hose going to the heater core from the thermostat area IS hot, then the heater core is plugged probably.
You need to remove the heater hose while cool,from the thermostat area and remove the hose from the water pump area (that's the outlet of the flow thru heater core) AND THEN take a garden hose with p-is-tol grip type sprayer,and blow water back thru the outlet hose out the inlet hose. This will blow any bad plugging material out the way it got in.
Don't apply too much pressure if it is plugged bad. The heater core isn't made to stand 50lbs. water pressure. don-ohio (:^)

Heater blows cold


Check the heater matrix valve firstly for it's valve operation and cable operation. Also check that the heater matrix isn't clogged with hair and gunk. this can dramatically affect how much air can blow through it.Check that the pipes leading in and out of it are hot from the engine. If not, then check your engine for coolant leaks, blockages and running temperature. If your engine isn't getting up to heat, then neither will your heater. This could likely be a thermostat which has failed.

How to fix your heater in a 2005 mone carlo


I would need some more clarification to get you a 100% answer but based on some assumptions I can give you 2 possible solutions.

It is possible your blower isn't working. You going down the high way is getting enough air through the venilation to bring heat into your car. If this is the cas while you are parked turn your blower setting down to the lowest point. Listen then turn it up to the highest setting and listen again. If you don't hear a fan running on the highest setting you need to replace the blower.

The other possibility off the top of my head is a bad thermostat. Your car isn't getting hot enough to trip it until your on the highway. If this is the case simply replace the thermostat.

I have a 1994 Jeep wrangler 6 cylinder. I replaced the cooland and therostat and it opens like it should at about 100 but the air is still cold. Is there something I overlooked?


Hello! Thermostat should be a 190 degree...you may have an air blockage...Remove radiator cap start engine and leave cap of until all air bubbles are out (even after thermostat opens)...Cap and test for heat...if there isn't any heat...When that thermostat opens and hot water flows through the upper hose of the radiator that hose will be hot and hard..If you feel the heater hose only one will be hot which means that nice hot water is not passing through the heater core...That could be due to blockage or the control in the car isn't opening the valve on the core...check to see if the heat control is opening the valve...If it is, I would suggest that you purchase a back flushing kit ($10) A plastic tee fits into the inlet heater hose and a garden hose is then connected to the tee...Drain the radiator, remove the thermostat, and turn on the water...do this with heat control on high...The system will back flush out of the top of the radiator and hopefully clean the blockage...Reassemble ...Cap off the tee (cap is in kit)...Install thermostat (190) Is a better choice...Refill radiator...Start engine and leave the radiator cap off until all the air bubbles out............At that point you should have heat...Guru...Saailer

My heater is not getting hot


Hello! There are only a few reasons for this awful event to occur in early December...Either Hot water isn't circulating through the heater core, the thermostat isn't opening or the door that directs heat is faulty...Is the temperature gauge showing normal? Next, is the upper radiator hose hot and hard? If the last two answers are yes then hot water is circulating...The unit that controls the doors ...ie...heat or defrost is called an Actuator...Also the lever that opens the heater may be at fault....LETS ELIMINATE...
Is there defroster heat? If no the heater core isn't opening ..If yes then the actuator is the culprit...You can check the heater by feeling of each of the two hoses that come through the firewall into the inside...If they are both hot then the heater core is open and functioning...If one is cold the heater isn't being opened by the temperature control..Or it is simply blocked with gunk....It's a 99 and getting old...I would suspect that IF the upper radiator hose is hot and hard and the temperature gauge is normal all is well with with most components and the next step is; Are both heater hoses hot...Your going to have to narrow this down for me to pinpoint the cause...See diagram below of the door actuator allowing defrost heat to be sent to the heater floor duct...
Send a comment with results and or observations...Remember"your my eyes and my hands"...Guru ...Saailer

Heater blows cold air in 98 s10 blazer


Pull thermostat out and check to see if it is stuck open. If it isn't, put thermostat in a pot of water and heat to boiling. If thermostat opens before boiling it is fine. Reinstall thermost or replace it.

Heater will not blow out hot air in my 1988 ford F250. Thermostat and hoses are all good. Is there a sensor that may be causing the problem and where is it located?


Hello! There isn't a sensor that would disallow heated water to circulate through the heater core...If the temperature gauge rises to normal...And the upper radiator hose is hot along with the lower hose ...I can conclude water is circulating through the block...Question then becomes; Is it circulating through the heater core? And the answer to that is, I don't think so...With the heater control turned on high feel the outlet heater core hose (facing engine it's the one on the left) if it feels cold or not as hot as the inlet then one of two items are at fault...#1...The Plenum assembly, which the heater core sets in has an open vacuum line...#2...The heat control valve cable or the valve itself is not opening...See picture of valve below...It is on the firewall...Let me know if heat is passing through the heater core...If hot water isn't passing through the core and the valve is opening than the core itself is blocked...send a comment...Guru...Saailer

Heater stoped blowing out hot air


Your problem can be caused by a bad thermostat, bad heater control valve, a heater door that's not opening or a clogged heater core. If the thermostat is good, check your heater hoses when the heat is on. Both should be hot; if one isn't there is a vacuum operated device inline with one of the hoses (heater control valve) make sure the vacuum line is connected to it. Sometimes you can manually force the valve to move; if you can do it and see if the 2 hoses get hot as a result. If they do, change the valve. The heater door is inside the vehicle and it too is usually vacuum controlled and often somewhat involved to service. I'm not sure of the exact configuration of your heater core but they too can become very involved to replace. More than likely the heater core isn't clogged and there's a very good chance you just have a sticking heater control valve.
