2007 toyota camry LE 2.4L does it have a heater control valve?


There is a blend door in the heater box in the passenger compartment. This door mixes the air from the outside and routes it through the heater core. If it is stuck, then no air comes through the heater core. Check for the levers under the dash by the center console and see if they move.

I have a 92 Pontiac Sunbird SE. Blows hot air but very week. I replaced the blower motor and sensor already. I can hear the motor running the way it should but it is not blowing hot air in the vents for...


Does the car have A/C? I've seen where the A/C evaporator coil springs a leak and it will be soaked with refrigerant oil, then every speck of dust or dirt that comes along sticks to it. Pretty soon it's plugged solid, the air for the heater has to pass through the A/C coil along with the heater core. No A/C, it could be that heater core fins are plugged. Also, some cars have a "cabin filter" if that's plugged it won't allow air to enter the system at all. Call a dealer or auto parts store to see if vehicle is equipped with a cabin filter. Good Luck!

Air feels cool, but not blowing enought air


I worked at a Dodge dealership for a while and 9 out of 10 times this is due to the recirculation door being broken, allowing hot air from outside to enter the cab of the truck. The dashboard will need to be removed to access the area.

A/c blowing hot air but it has freon in it.


is the compressor working and pressurizing the freon --- is there air in the system along with the freon preventing the system from circulating --- is the heater control or vent closing --- are the evaporator coils/fins clogged or dirty -- are the air conditioning selector controls properly actuating vents for mixing inside and outside air and closing off heatter vents --- need more investigation on your part

Heater not working


I would check if your vent to the outside is open. If it is I would check the vacum hose that controls the vent to open and close.

Fully warmed up; blowing hot and cold; Suzuki XL-7


Its just a vent damper plate not operating, it's like a gate which controls the flow of air,,usually they are operated by vacuum, or cables.
Service center time, unless you are handy with your own repairs.

Heater problems


I believe you have one of two problems either your heater core is plugged up and not allowing enough flow or the temperature blend door located under the dash is not moving.The heater core is easy to check,A quick check of the heater core is with the engine running and with the blower motor off or on low carefully chck to see if both heater hoses are equally hot if not remove them from the heater core and use a garden hose to backflush it the blend door can be more of a hassle as it can be operated by a motor or vacuum servo and even a simple cable these also have been known to break but with the blower on high change the temp control from cold to hot and see if you can hear a change in the sound of the blower and sometimes you can hear the door shut it more than likely the door is ok but you will need to check it and see.
Good Luck
