2009 Camry won't blow hot air
Can't get hot air when heater is on. It blows cold air
when a/c is on but no hot air. Fluid level is good,
replaced the thermostat and flushed the heater
core. Any thoughts?
blocked heater unit or malfunctioning switch
After the car runs a while feel the radiator hoses. Both should be very warm. Are they
Your description suggests the Cooling System has been serviced in an attempt to correct this condition. Am I correct. If Yes...then...now its time to check out your computer controlled HVAC System. Most would diagnose this issue with a Bi-Directional Scan Tool. This tool can be used to check the operation of the BLEND DOOR. Also...there may be a factory service bulletin which would describe how to fix this issue. More research suggested.
Above answers are great. A simple way to check if the heater core is getting hot water is to touch both heater core hoses once engine is warmed up. they are usually located on the right side firewall and are about 1 inch in diameter right next to each other. if both hoses are warm to touch then water is going in/out as it should.(Suspect the heater controls or blender door). If only one is warm (with interior fan off), then suspect a blockage in the heater core. Hope this helps.
Make sure your heater controls are turned to warm, fan off.
Don....did you ever figure out a solution to this problem?
