Why is my radiator blowing cold air?

A car heating system blowing cold air can be due to a faulty thermostat, low coolant fluid level, malfunctioning heater core, a leaking cooling system, or problems with heating controls and blend door.

Can a clogged heater core cause overheating?

Engine Overheating Even a clogged heater core has the potential to obstruct coolant flow enough to cause overheating. A low coolant level (caused by a leaking heater core) can lead to overheating and possible engine damage.

Why is my Chevy Tahoe heater not working?

The only thing that the air conditioning system has in common with the heater is that they both use the climate controls and the blower motor. It is entirely possible for your Tahoe’s heater to work just fine even when the air conditioner is not blowing cold at all.

One of the most inconvenient vehicular problems is when the A/C won’t blow cold air. If your Chevy Tahoe isn’t keeping you cool, we’ve outlined some of the most common reasons why this might be happening.

What does it mean when your car heater is blowing hot air?

The heater is not blowing hot air either. When a car overheats, it is an indication that there is a problem with the engine cooling system. The purpose of the engine cooling system is to keep the engine at a temperature that is consistent.

What to do if your heater is blowing cold air?

Coolant level: If your coolant level is low, your heater core may not be getting enough warmed coolant through it to produce adequate heat. Solution: Top up the coolant and see if it helps. If the level is low due to a leak, track down the source and get it repaired.

Start the engine with cap still open and let the engine idle for a few minutes. If the coolant level should drop as the thermostat opens, top it up as necessary. This should bleed off the air bubble. When the engine is fully warmed up, put the cap back on and take a drive to see if the heat output has returned.

Why does my car fan keep blowing cold air?

Engine fan: Most vehicles today have a thermostatically controlled electric fan that comes on when additional engine cooling is necessary. A defective thermostatic switch could make the fan run continuously, reducing the coolant temperature to the point where you can’t get enough heat into the interior.
