Why is my car blowing out cold air when the heat is on?

Low Coolant Level The coolant (usually a mixture of water and antifreeze) in your engine doesn't just work to keep the engine from overheating: It's also the source of heat supporting the heating system. If there isn't enough coolant in your system, the heater core will blow cold air into your car.

If your radiator is very low on coolant, you'll get no heat. If your levels are okay, you either have a bad water pump or a thermostat that isn't opening.

Can a fuse cause heater not to work?

Faulty Wiring or Blown Fuses Similar to your broken HVAC controls, your car's wiring could be broken or have a short in it. This would mean the heater isn't triggered when the driver commands it to function.

How do you check if a thermostat is working?

Check the screen: Check the screen of the thermostat and make sure that it is lighted. A blank or unlighted screen could indicate a thermostat failure. Check the batteries: Many modern thermostats rely on battery power to operate. If the screen is blank or unlighted, a battery change could solve the problem.

Why is my car not heating up in cold weather?

If it is stuck, it may be allowing the coolant to always be run through the radiator, which keeps it too cool to allow for heat in the cabin but will still allow the vehicle to run. John Paul, The Car Doctor, told us, “The most common issue with poor heat in cold weather is due to a malfunctioning engine thermostat.

How do you fix a low coolant cap?

Place a bucket underneath the radiator and drain the coolant by detaching the hose. Remove and replace the thermostat. Reattach the hose to the radiator. Add the coolant and place the cap back on the reservoir. Lower your car. Start the engine. Wait to see if the heat comes on. Take a test drive. Check to make sure the coolant level hasn’t dropped.
