  • rich cummings Jan 03, 2014

    the temp cable is connected at the dash mounted temp contrl cluster but i can't tell if the blend door is operating near the heater core

  • alberto anicolas Jan 04, 2014

    if the " blend door " is the flap that lets air flow/heat through then see where the control cable attached to it (at firewall) has free movement fully open&fully closed by disconnecting where it moves to see if there's obstruction from the cable moving it OR flap is obstructed from its complete positions as it should be. Hope this helps.

Blend door is inside the heat/ac box that contains the heater core that you changed. It is vacuum operated, so check all of your vacuum lines. There is a vacuum line that goes thru the firewall, right above or below the 2 heater hoses.

Check to make sure vents are not clogged,below window by wipers check that and vents from dash going down,If not plugged then probably your heater core or heater blower motor may be shot or weak,you need a Haynes manual to check these if you are not familiar with where these are located at.Haynes manuals can be bought at most auto parts stores

Try checking the thermostat in a pan of water, on the stove, with a thermometer to see when (IF) it opens. If it's NOT the thermostat try flushing the heater-core (buy a kit and use a garden hose).

2001 hundau elantra have no heat have replaced radiator termostat water pump heater core an hoses the hoses stay tight


If the cooling system is full, and the heater hoses get hot when the engine warms up, you may have a problem with a blend door under the dash.
The blend doors direct air thru the heater core and the vents.

No heat for 2000 lincoln ls


You have a defective air temperature control blend door actuator or blend door is jammed due to heat warping. To replace the blend door requires the entire dash be removed form the car.

02 maxima blows no heat. Only one hose going to core is warm. Have new t-stat and new radiator. I'm having trouble locating blend door. Still don't know if that's the problem.


If only one hose going to the core is hot, then the heater core valve is bad. It's what stops or allows hot coolant into the core. Only one hose being hot means coolant is not traveling through the heater core. Have that valve checked out.

I have a 4cyl 1999 Jeep Wrangler. The heater only blows warm air, no hot air. I have back flushed the heater core with a garden hose and there was no clog. I have checked the t-stat and it is...


The key is the heater hoses. The top hose is the inlet for the heater core and the bottom is the return line. If the bottom hose is not hot, there is little flow through the heater core. It does not have to be completely clogged to reduce the heat output. The core needs to be flushed multiple times IN BOTH DIRECTIONS through the heater hoses. If this does not restore the heat, try a commercial/radiator flush. Many people have had alot of success by filling the core, through the heater hoses, with a CLR type product and letting it sit for 10-15 minutes to remove scale followed by a thorough flush.

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

1994 pontiac firebird HAS NO HEAT


Okay. warm up vehicle, get radiator hoses hot.  Turn on heater, fan on low.  Grip both rubber heater hoses close to the firewall, from the engine compartment side.  They should be too hot to hold for long.  If they are not hot, then you have a lack of coolant circulation to the heater hoses.  If they are hot then access heater core, behind glove box area.  Blend door which moves as you chose HOT or Cold, should be cable controlled, move the controls and be sure the door is actually moving. Keep me posted
