So maybe it's the blend door. The manual I'm looking at indicates your blend door is cable actuated. Maybe the cable sheath is loose such that the cable is not moving the door. See if you can access one or both ends of the cable to see if it's working. If nothing else, you could take the cable off the door and see if you can open the door by hand to see if that will get you hot air. Please let me know if you have more questions.

Heat stopped working in 2000 pontiac sunfire


With blower on high and tempature to max heat check to see if you have good air flow in all mode selections (defrost, vent, floor etc.). If so and you still have no heat then check heater core hose going from engine to inside car to heater core with vehicle running and coolant tempature about half on guage. If both hoses are hot and coolant in radiator/overflow bottle is full then hot cold blend door is stuck in cold position. If coolant level is low you will get no heat, check coolant level first.

1997 Camry 4-cyl fan works but heat very weak - coolant level ok


Probability 1) The thermostat is probably stuck open, coolant is not getting hot enough from the engine to provide heat.

Starting from cold, allow the engine to run and warm up. While doing this, feel the upper radiator hose - you should be able to feel the coolant heating up to the point the hose is uncomfortably hot. If it gets that hot, then go to next step.

Probability 2) The heater core flow is restricted, not allowing full flow of coolant into passenger compartment.

There are 2 smaller heater hoses that run to the firewall. Are either of these hoses getting hot? Both sides hot indicate full coolant flow. Both sides cool indicate heater control valve not opening fully.

No heat- we have replaced the thermostat and checked heater coar and fluids and only about 10 percent of the time it blows heat


I think that there is a switching valve on the heater hose assembly. If it has this valve this is why there is no heat.

88 Celica has no heat. AC works fine. Any ideas


the a-c and heater run on 2 different systems the heater needs coolant going thru the heater core to make heat by blowing air through it and the a-c uses it's own sealed system to cool the air so if you have no heat / it has nothing to do with the a-c working or not . first thing you do is check the cooling system like rad and coolant levels . you will have heater core hoses running from the engine to the firewall going to the heatercore . grab the heater core hose and feel if it's hot . if your hoses are hot then the heater core is bad or the blending doors are stuck .
