96' Has No Heat??

Hello everyone.
My 96' will not blow heat out of the vents, it does blow air that is barely warmer than the outside air. I have replaced the thermostat 3 times, flushed the coolant and made sure the coolant level was topped off at all times. My truck has had no heat since October. I work in Tn. so when I get the Holidays off I go home to Michigan, I'm tired of spending all of my holidays working on this thing I would love to come home and be able to drive my baby instead.

Does anyone have any idea what other than a thermostat could make a truck not blow heat??? I would love to go home for Christmas with a new plan of attack for this problem. Thanks in advance!

Nick

Sounds as if the heater core is stopped up,Are both heater hoses same temperature after complete warm up?If thats the case ,try flushing the heater core alone with a garden hose,and if you are lucky the core won't blow apart and you will have heat! Just my two cents worth.Second thought would be the temperture control valve that regulates the flow to core,but don't I know where that is "yet".Hopes this helps

There is no temperature control on these trucks , if you arent getting heat your heater core is clogged. OR the temperature control flap in the ventilation system might be malfunctioning, check the heater hoses to see if they are getting hot first

Man, I was hoping no one would say anything about heater cores, I hate those things. It seems logical for the core to be clogged/corroded, the truck is low miles, but it is almost 14 years old. Thanks for your suggestions.

try flushing it out first, worse comes to worse, you have to replace it

Just like everyone has said.... heater core - check the two hoses going to it to see if they are the same temperature when it is all warmed up.... Other thing to check would be the blend door under the dash. It is cable operated (IIRC) from the thermostat knob to the door that opens/closes to regulate the amount of air that gets directed through the heater core.

Thanks for the advice guys, I put a new heater core in and it fixed the problem! While my baby is in my buddies barn I am working on the glow plugs, the glow plug relay and changing the oil.
