2002 Dodge Intrepid has no heat

Bad coolant flow. check for low coolant, also a thermostat could be restricting proper coolant flow. If coolant is full in the radiator than touch your upper radiator hose to see if it is hot. If their is proper coolant level and engine is warmed up to temp and radiator hose is cold replace your thermostat.

Could be the heater bypass valve is stuck or the heater core is blocked.
I'd check the heater core first.You may have trapped air in the cooling system or the heater core may be partially plugged up. Engine coolant is delivered to the heater core through two heater hoses. With the engine idling at normal operating temperature, set the temperature control knob in the full hot position, the mode control switch knob in the floor heat position, and the blower motor switch knob in the highest speed position. Using a test thermometer, check the temperature of the air being discharged at the HVAC housing floor outlets.
Temperature Reference
Ambient Air Temperature 15.5° C (60° F) 21.1° C (70° F) 26.6° C (80° F) 32.2° C (90° F)
Minimum Air Temperature at Floor Outlet 52.2° C (126° F) 56.1° C (133° F) 59.4° C (139° F) 62.2° C (144° F)
If the floor outlet air temperature is too low, Both of the heater hoses should be hot to the touch. The coolant return heater hose should be slightly cooler than the coolant supply heater hose. If the return hose is much cooler than the supply hose, locate and repair the engine coolant flow obstruction in the cooling system.
OBSTRUCTED COOLANT FLOW
Possible locations or causes of obstructed coolant flow: Pinched or kinked heater hoses. Improper heater hose routing. Plugged heater hoses or supply and return ports at the cooling system connections. A plugged heater core. If proper coolant flow through the cooling system is verified, and heater outlet air temperature is still low, a mechanical problem may exist.
MECHANICAL PROBLEMS
Possible locations or causes of insufficient heat: An obstructed cowl air intake. Obstructed heater system outlets. A blend door not functioning properly.
TEMPERATURE CONTROL
If the heater outlet air temperature cannot be adjusted with the temperature control knob on the A/C Heater control panel, the following could require service: The A/C Heater control. The blend door actuator.
The blend door. Improper engine coolant temperature

Could be the diverter valve. It's the one located near the firewall in the engine bay. The valve is in-line on one of the two coolant hoses that run through the firewall. Have a helper rotate the temperature knob back and forth, with the ignition turned on, and you watch to see if the valve is being adjusted. I'm guessing it isn't. Sometimes the cable pops off its perch, other times someting is broken on one end of it or the other. Plastic parts are often used in this assembly. Best of luck

Okay, The water pump is more than likely okay but at this point I would not rule it out completely. One simple check to see if the water pump is moving water and that the thermostat is opening and closing is to take off the radiator cap when the car is cold. Start the car and stand at a point where you can see down in the neck of the radiator without looking straight down into it. When the thermostat opens you will see the coolant level change dramatically when the thermostat opens, you should be able to see the coolant being pumped through the coolant tubes in the radiator. IF you see the coolant level change and then see the coolant being pushed through the coolant tubes, then the water pump and thermostat are probably okay. If they appear to be working okay then the next thing is to check the heater hoses to see if they get warm. Do not grab either one while the car is at normal temp as they can be very hot. Let the car cool down for about a half an hour then see if they are both warm. If they are, then I would move to the inside of the car and check the heater controls. There may be a malfunction in them. The reason for this logic is that if the water pump is not operating properly or the thermostat is not functioning properly, Chrysler will usually turn on the check engine light indicating a problem. They have sensors in the engine that tell if the coolant is to cold or to hot (these are not 100% accurate but in most cases are). The heater controls on the other hand are not tied into the check engine light so if there is a problem there, you will have to do some digging to find the problem. If the heater one of the heater hoses is cold and the other is warm after running the engine then the heater core is probably plugged up not allowing the hot water to move through the core to produce heat.

Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.

I have a 98 dodge intrepid wjth a digital temp control Icann't get heat when I go up with temp or in manual over ride.Line's to the heater core are hot both coming and going.Checked # 17 fuse its good.Could it still be the heater core??

The clicking noise is the motor for the "blend door". The heater core and the air conditioning side share the same ducting. When you move the knob a small motor moves the door letting the respective hot or cool flow happen.
The heater core is probably blocked. The engineers at Ford have the coolant hoses bypassing the core with a WYE at the firewall. The coolant takes the path of least resistance and stops FLUSHING the heater core and it eventually clogs.

ck the coolant level, if low, top off and ck for leaks. then see if the heat comes back. if coolant level is good and engine temp guage is in the middle, flush heater core. if engine temp is too low, replace thermostat.

coolant level is fine still no heat
