2008 land rover sc warm up car turn on heat blower working warm air at first then clod no heat


When is the last time you change the thermostat and coolant?
Recommended interval is 2 years.

Coolant is the heat carrier to heater core.
Top off the coolant level for now and re-test.

Heater is just warm, when you turn on the defroster on high takes a long time to defrost. I have had the car since 2007 and this is not normal. p.s. already changed the thermastat


You could possibly have a bad heater control valve if the car has one. Another item maybe a stuck or faulty blend air door. This would be the actuator most likely. It may not be shutting off all the way to allow complete heat through. The other possibility is a partially clogged heater core.

2002 ford escape periodically over heating


Check the thermostat and the fan too. Overheating nothing to do with the heater core, even if you shut the heat off, the car should not overheat

I have no heat in my 2002 Dodge Stratus. I have changed the thermostat and flushed the heater core? What else could this be?


See if your library has a Stratus shop manual and check the heating system chapter. You didn't say if the engine was reaching operating temperature or not. If the engine is warm but you are not, I would say the problem is in the heat exchanger somewhere. If your engine is cold, you can't really expect the heater to get warm, now can you. Then you have a different problem to chase.

Lack of water on your floor means your heater core is not leaking. It could still be plugged somewhere. The fact that you get some heat initially, but it turns cold when you turn the fan on, sounds like a lack of adequate warm water to the heater core to me. If the engine is warm, it could be a circulation problem of some sort.
