Blower working but dont have no heat i changed the thermostat still not working im hoping its not heating core any suggestions

Also it may be a jammed blend door.

Ok, here is my take on your problem. As you may already know, it takes a car a few min. to actually warm up to operating temp. When the coolent reaches operating temp. the thermostat opens to circulate the coolent in the radiator. Now, as your drive, the air pushing against your car will actually blow some air through your heating system ducts and into the passenger compartment. Is it possible that your blower fan isn't working? Because while you are stopped, there would be no air forcing its way through your ducts, thus no heat. As your drive, your car gets up to operating temp, heats up, and the air pressure as your drive will blow some heat out into the passenger compartment? On a side note, if your thermostat is stuck in the open position, it would take it forever to warm up since it is circulating ALL the coolent even tho it isn't at operating temp. A thermostat stuck open will take 30 min or more before you actually feel any warmth, if at all in the winter.. your thermostat opens and closes constantly as the engine is running to keep it at its normal temp, usually around 160-180 degrees. If you live where it gets really cold, a thermostat stuck open likely will never get warm. If your blower motor works, and your engine don't overheat, im 98% sure its your thermostat.

If you have no heat in your vehicle then it is probably the heater core which is just a small radiator that sits behind the glove box. The thermostat itself is probably located where your top radiator hose connects to your engine. It is an easy and cheap fix, just pull the hose away after undoing the clamp and you should see it. If it is not there, then it will be in the bottom hose. Hope that helps you out.

May need.heater core flushed out.

water passes through the heater core VIA radiator if water is not heating up you will only feel slight heating or no heat possible cause is a bad thermostat water free flowing through radiator and engine not getting a chance to heat up enough. have radiator pressure check or just replace thermostat there cheep usually $8.00 to $15.00 you do have a Mercedes like Cadillac and Continentals parts cost more.

good luck, hope this helps (PTL)

A few things you may try before the expense of a heater core, and the labor putting another one in.
First, I just want to mention I have used Bardahl stop leak, and it worked very well for me, It's a good product. Also, you're right, the a/c commpressor is a seperate issue.

Now, you mentioned you changed the thermostat, the following test is just to make sure it's working properly, and to check the coolant circulation.

1. With the heater temp and blower off, start your vehicle and let it run 6 to 8 minutes to allow it to reach normal operating temperature. then;
turn your heat temperature and blower wide open, when you do, listen very closely in the engine compartment, you should hear a small click from the thermostat opening up to allow ciculation of the coolant.

2. Turn the engine off. Carefully reach behind the engine, at the fire wall where your inlet and outlet hose, ( both about 1 inch in diameter ),hook up to your heater core. feel each one of the hoses. If both are hot, then your coolant is circualting through the core. If only one of them are hot, then the coolant is being blocked from circulating through the core, and if that is the case I would probably try flushing the whole cooling system first.

I hope this helps.

Hello Amber. When you have no heat, change the thermostat. It is probably stuck in the closed position so no hot water is circulating into the heating core. Joe

thanks for choosing Fixya!!

flush the heater core its more in likely clogged. Google heater core flush.

Location of components...

Check the 'heater control valve'. This valve opens when u turn on the heat switch on the dash, so the hot coolant will flow thru the heater core and provide heat. So although the coolant is circulating in the engine, the valve controlling the flow to the heater core is stuck closed, or not working.
