It may be the heater matrix. It` a small radiator just like the one under the hood.
The feed pipes can be found under the hood.
Remove them and flush it out with a garden hose before you attempt to replace it

Is there a relay for the heat,sometimes there is heat sometimes not. one heater hose hot one warm. or is the heater coil clogged


Probably the heater core. I backflushed my Dodge Dakota and that fixed the problem. Determine which hose is the supply and the rerurn hose. Take them both loose and back flush with your outside hose pipe. Do NOT turn the hose on full blast you could damage the heater core. I opened my hose bibe 1 turn open after fitting a connection to the heater hose. I back flushed, then forward flushed and back flushed a 2nd time. I saw it done on You Tube. Fixed my Dodge! Blows HOT air now!!

Heater not getting warm


The first thing I would check would be the valve that feeds the coil. Is it opening when you turn the heat on? Also, I had this problem in an old car of mine and it turned out to be a clogged hose feeding the heater coil.

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.

How do I check to see if the heater coil is plugged


The fan is usually the problem - does the fan run? If the fan is good, remove the fan and use a mirror and flashlight to inspect the coil. It would be unlikely that the coil is completely plugged but it can happen.

Which hose will be in and the out from the heater coil. I was told to find the out hose (heater coil) and blow air into it and disconnect the in line, this might get the clog line unplug.


Core, not coil. The inlet line will come from upper part of engine, usually from the intake manifold, or a cylinder head fitting. The outlet line will end up near your water pump, where the lower radiator hose connects to engine. Hope this helps you.

Heater is blowing but no heat! 1996 grand am


If the car is warm and its probably a bad heater coil the other options are the the water is not cisculating due to a stuck thermostat or water pump is not working but these problems usually will cause the car to run hot also if it not running hot then your haerter coil is not working.

Heater is warm then stop and its cool


Age of the truck, probably clogged heater coil. Find where coolant runs in and out of firewall under hood. Try "backflushing" with a hose and collect the water as it comes out. You'll probably see sediment and lime build up from so many seasons. The water pump isn't pushing as hard so you might not be getting flow through the heater coil as much as when it's revving higher.

Pull to a stop light and the heater starts blowing cool air


sounds like you need to either...add anti-freeze solution to your radiator...or worse case...coolant pump is starting to fail or heater coil is clogged..if coil is suspected to be clogged....do a radiator flush...reverse and foward flush the coil only...hope this helps
