This is provided you have confirmed that a plugged or partially plugged heater core is your problem, and not a vacuum problem, or heater control valve or similar is not defective. Yes it certainly sounds like some blockage/restriction there, but may I advise you to try this first, as it may save a lot of money, time, & aggravation. Go to Rona, Home depot, or similar hardware store & buy a drill pump. (about $25.00 in Canada) but there are cheaper ones around.
Remove your heater hoses at the firewall (when engine cold) and you will see the 2 copper ends of your heater core to attach drill pump to. Put one end of the pump (pressure side) on one fitting, of the core and the other hose from pump suction side, into a jug of CLR (calcium ,lime, rust, remover.) The other connection/fitting from your heater core will need a piece of hose going from it, into a pail, or another jug, same size as CLR to retrieve liquid when it flows through. Circulate the CLR through the core a few times, then let it sit in the core for a while. Then reverse the hoses at the core & circulate it through the other way a few times & let it sit in there as well. I let mine fill the core, then I plugged line where CLR would flow out of heater core & then let it sit all night in there to dissolve as much calcium etc., inside as it could. Then next day, I ran pump in both directions/fittings, again to flush everything out. Then I re-attached my heater hoses. My heat increased at least 75% at idle, because it had removed a lot of the restriction in the core.
Make sure you take all safety precautions, such as eye protection in case CLR splashes in your eyes, and make sure engine is cool, pressure is relieved via removal of rad cap & to avoid burn from hot coolant when hoses removed. My guess is that your into $20-$25 tops, and a whole lot less work. Let me know how it goes.

    Sorry, here's a picture of type of pump I'm talking about. As long as it will circulate some liquid for you, use whatever you have, or want to.

I'm not a mechanic but i have the same problem i took my dashboard off so i could get to the heater controls and i unplugged the fan control and the selector switch. Then i plugged them back in and the heat came back on full blast rpm unrelated so you might want to check your heater controls to plus always look for TSB(technical service bullentin) and recalls

01 dodge Durango heat isn't blowing hot air


Check hoses to heater core to make sure BOTH are getting hot. If yes, bad blend air door or actuator likely. If no, back flush heater core or replace.

I have a 99 durango i have replaced heater core water pump thermostat and all hoses still barley any heat just warm vehicle comes up to normal temp does not over heat but still no heat please help


Are the heater core hoses getting hot? That could be a blockage in the intake manifold or engine block. Is the blend door sticking? That would be one item that would make for lukewarm air if the hoses feel nice and hot when up to operating temperature.

Make sure coolant level is ok,check the thermostat and/or replace with a higher temp thermostat that should help unless it is a circulation problem in which case flushing the system may be needed

Can i still drive my 99 dodge durango with a bad heater core?


well if the heater core is leaking then your coolant is leaking as well, heater cores leak on the inside of your car so your car will get water damage and will smell like antifreeze, so i wouldnt drive it

1999 Dodge durango heating sucks and leaking coolant now


Smelling antifreeze indicates to me you have a crack in the heater core. Most are made of plastic. This shows yours is metal. I guessed on 2WD or 4WD and size of engine.

Unlikely to be frost plugs unless you ran the system without antifreeze and the block partially froze. When they freeze fully, the plug pops and out and you lose all the coolant when it thaws.

Finally, this is a common problem with the Durango! As my learned colleague says, replace the thermostat as it needs to be fully open to let water flow well to the heater core.

Make sure you chek out the coolent level and if the level is fine, the next step to go is the heater core. it should be one of these 2 solutions!!
