My Heater in my 88 Hatch doesnt seem to blow enough heat....its more of a luke warm.

This is an issue to me, because my windows wont defog.....mainly the drivers window, and with a climate that rains 80% of the time, its definatly an issue.

My 89 Hatch blows just fine, and defogs quite a bit better.


Now all the cables are attached to the heater motor, and the hoses entering the heater core, and leaving the core, are Both hot/warm.

What else could be the issue ? A thermostat should be the issue should it ? The temp gauge is half way up the meter.

Thanks

I'd check for a coolant leak. I had this happen to me in my CRX. I gradually lost heat over several days because less and less coolant was passing through the heater core. This also meant less coolant to cool the engine, resulting in overheating. I also blew my headgasket. Now my car sits awaiting either a headgasket change or a complete engine swap.

 

well...I know its not leaking coolent, because there would be this mysterious green liquid running from my car......and I just built my engine, and its got new seals top to bottom, new hoses front to back, and a fresh radiator.

 

try manually moving the heater valve it maybe stuck

 

Check that heater valve under the hood..And behind the center console there is a little white arm,,Sometimes it gets loose and you have to re adjust it,, ..

 

lol I be glad to join you...I cant figure out why my blows only warm too...i replaced the thermo with like a 190...replace heater valve and have brand new heater climate unit...also new wires...I am guessing something in heater box no opening or closing any ideas????

 

im having the same problem but my thermostat is good and coolant level is fine
