Why is My Car AC Blowing Hot Air? - BlueDevil Products

the temp rod got knocked off. if you look to the right by the gas pedal you should see something not attached.

Check for correct coolant mixture. Also you could have a thermostat that is stuck completely open causing it to flow straight threw the engine block, cylinder heads, heater core, an radiator without stopping long enough to heat the coolant up to provide cab heat. It could also be a clogged heater core. Or a blend door on the HVAC box that is not allowing the heater core door to open. Hope this helps.

This will help.Thanks.

Heat and air conditioning are in separate systems. If you aren't getting heat, the first step is to check your coolant level. Low coolant can result in improper flow through the heater core. If you do have low coolant, be on the lookout for a coolant leak! If your coolant isn't low, then there is going to be an issue with circulation through the heater core. The heater core could be clogged in some way or another.1

the heater core is clogged. the heater core is like a mini-radiator that heats up the air blowing through it by cycling hot coolant from the engine's main radiator into itself.

First check and make sure your coolant is full. This is the most common cause of cold air coming from the heater, because the hot coolant provides your heat. If it is low, no heat. If your coolant is full, it could be your heater core, which is a big job on almost any car.

Hope this helps!

Check the metal part of the heater core lines at the firewall if you can get to them and see if one side is noticeable colder than the other. At least one of them should be hot or you have a bad thermostat. If both are hot than your hot/cold actuator inside is having a problem

Have you checked the heater tap to see that it is working?If the heater tap is working you can undo the hoses at the firewall and use a garden hose to check that the water is flowing freely through both the heater radiator core and the engine.poke the garden hose up one of the hoses you removed and turn the water on make sure water is flowing freely out the other hose,if clear repeat test on heater radiator core.If heater core is blocked and you have compressed air you can gently flush the core by blowing the water through it.
