To check the heater core in a 2005 Chevy Equinox, first ensure the engine is cool and then inspect the coolant level in the reservoir. Look for any signs of leaks or dampness around the heater core, typically located under the dashboard on the passenger side. You can also check for warm air coming from the vents when the heater is on; if it’s not functioning properly, there may be a blockage or a failure in the heater core. If issues persist, consider flushing the heater core or consulting a professional for further diagnostics.
