As a test, restrict a good portion of front of radiator with cardboard. is the engine running at 195 degrees? if engine temp is good, verify that both heater hoses going to heater core are hot. maybe heater control valve.

Have your coolant system flushed then if the problem still exists then replace the heater core because it is clogged.

You may have a heater valve that is on one of your heater core hoses may be bad.

1999 dodge dakota blows cold air at idle but heat warms up when revved. would like a solution to this heater problem. I live in alaska and need the heat to function properly. already flushed the heater...


Sounds as if the engine is not building up temp due to cooling system working. If engine temp gage is reading low try covering 1/3 of radiator with a piece of cardboard "Bumper side" to reduce the cooling effect.. just watch temp and out side temps if warming up outside or heavy driving remove the blocking to allow full cooling

My 03 G35 is overheating and no heat in the cabin


Hello,
The thermostat was a good choice however you should go to a service station and get a complete cooling system flush.
your heater core and or radiator could be clogged.

Response to high running temp. And my problem is my heater core.


it seem that the root of your problem maybe caused by by radiator the heat exchange maybe restricted by dirty fins or corroded passages with in the radiator. This is proven when your temp goes down when your a/c is on. the airflow increases when the a/c fan is on. also make sure your fan turns on high when engine is hot. The heater core problem maybe caused by the removal of thermostat. the thermostat control the flow of cooling water and by removing it it forces more pressure to the heater core thus causing it to fail prematurely. you really need to fix the high temp problem, removing the thermostat will just contribute to more problem not to mention a slow warm up of the the engine (delayed heater reaction) and may contribute to high emmision discharge. The radiator usually cost around $150.00 + 1 hour of labor a lot cheaper than $300 - $500 bill to replace the heater core.

Not enough heat in winter


two things..make sure your cooling system is totally full and bled with the heater on.  Also your thermostat may be stuck open.  A flush before you change the thermostat wouldn't hurt.

1996 chevy corsica 2.2 liter engine. Coolant temp never reaches above one-quarter hot, therefore no heat. I've put in four thermostats, installed new radiator, disconnected the cooling fan, still no heat....


You may have a stopped-up heater core. It's a little radiator inside your dash; it's where the heat comes from. I don't understand why the temp gauge isn't reading any higher than that...

My 1999 chevy blazer will not blow heat


ther are two small tubes that open and close the valve to let in the hot air' one is from right under the carb intake and goes to the right (looking at the engine) right behind the fuse box. if there's o hole in that tube the heat will not work. just change mine becase the tube dry-rotted

NO HEAT


Les, it sounds like your blend door actuator has failed, it is a small vacuum operated diaphram up under the dash that controls a flapper that switches between the cool air and heated air. Good news is that it is an inexpensive part, bad news is pulling the dash out to get to it.
