Any chance you got an air bubble in the system? Try loosing the return hose from the heater and make sure your getting fluid through the heater core.

My 2008 dodge ram temp gauge goes from normal to high ,check gauge lite comes on in a few minutes temp gauge goes back to normal but heater will only blow cold air I,ll shut heater off wait a few minutes...

Souds like it's way low on coolant. The heater will blow cold air when the cooling system is so low that there is no water (coolant) running through the heater core. Then the thermostat opens, it trys to be normal but the system is low so it gets too hot in just a few minutes. If its that low, there must be a leak somwhere.

Sounds like a sticking/stuck thermostat.
Does your truck have cooling fans? If so, they should NOT be running when cold. If they are, you have a bad thermo sensor. If you have a temperature guage, what is it doing when you go from cold to hot to cold again?

1999 chevys10 4cyl. little heat, how do i know if it's the thermostat

First make sure the cooling system is full. The best way to test the thermostat is with a scan tool. This will plug into the diagnostic connector and give you the actual temperature when the thermostat opens. It should open at 192 degrees F. Without a scan tool you will need to resort to the old feel method. Start the engine cold and check the upper radiator hose as the engine warms up. It should feel cool and then hot when the thermostat opens. It should not gradually get warmer. Also feel the heater hoses. They should be about the same temperature. If one is hot and the other cold it means the heater core is plugged up.

My 2001 lincoln ls v6, the heater works fine except it doesnt blow out hot air. only cold, the car temp gauge is working normal too

It's possible the cooling system is just a little low on coolant. There could also be a valve in the heater hose that is failing to open and let the coolant flow through the heater core. It could also be the heater core itself. Did it start doing this gradually or did start all at once? If it came on gradually it most likely the heater core or low coolant, if it happened suddenly it's a valving or heater control problem. Good Luck.

4.6 liter has one heater hose warmer than the other. may be plugged core,or is ther a fuse to climate control switch?

Look for a heater valve on one of the hoses if there is no valve i would say its a plugged heater core.

Intermitant temperature

Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.

Check the heater core for a clog or the heater control valve. The easiest was to check these is allow heater to run for a few minutes and check the two hoses coming from under the hood against the fire wall. They should both be hot. If they are not, you have one of the above problems. Start with the heater control valve and replace it. It is much cheaper than than a heater core. Next, you will need to pull the lines from the firewall and see is rust starts coming out of the lines, if so, you may be able to flush the system and clear the blockage. After that, if it does not work, it will require replacing the heater core, which is no easy or cheap feat.

Let me know if there is anything more I can help you with.
