Why is my car AC blowing hot air and overheating?
Engine overheating can be caused by a number of things such as low coolant levels, a faulty thermostat, or a failing coolant fan switch. As mentioned above, this also restricts the warm coolant from flowing through the heater core which uses this to blow warm air into the cab of the vehicle.
What temp should heat be coming out of car vents?
Check the temperature with a thermometer inserted into the driver’s and passenger’s registers. Although many vehicles deliver a toasty 135° to 155°, 115° to 120° is acceptable. If the air temperature is okay but airflow is weak, the problem is the blower or a dashboard ductwork problem.
What temperature should air be coming out of vent when cooling?
If the AC system is operating correctly, then the air coming out of your vent should be about twenty degrees cooler than the regular temperature inside. So, if you’re cooling it and the house is 80 degrees, then you would ideally want the air to be about 60 degrees.

Why is my car a / C blowing hot air out of the vent?
Your car’s A/C system is one that operates a little differently than you might think. Instead of actually creating cool air, it instead removes the heat and moisture from the air inside of your car, leaving you with cooler feeling air.
What should temperature be coming out of vent?
In a normally operating air conditioner, the temperature of air coming out of the supply vents should be about 20˚F lower than ambient temperature inside the room. This means that if your room is currently at 90˚F, then the cool air coming out of the supply ducts should be at around 70˚F.
What should the air vent Temperature be in a car?
Place a probe thermometer into the lower air vents on both the driver and passenger sides. Any reading around 115F-120F (46C-49C) is acceptable. Some vehicle manufacturers boast their heaters will do 135F-155F (57C-68C) which would make things very toasty indeed.
What causes a heater to blow cold air?
The following are some issues that may be causing the heater to blow cold air: Low coolant levels. A plugged/clogged heater core. A faulty thermostat (thermostat that is stuck) Broken blower and/or blower motor. Heater core bypass hoses that have leaks.
