Where is heater core hoses located on firewall of 2005 Chevrolet equinox

The heat control valve on a 2005 Ford F-150 with a 5.4L engine is typically located in the heater hose that runs from the engine to the firewall. It is a small valve that controls the flow of hot coolant to the heater core.
To locate the heat control valve, you will need to follow the heater hose from the engine to the firewall. The valve is typically mounted on the firewall, near where the hose connects to the heater core. It may be necessary to remove some of the trim or other components in order to access the valve.

First check the anti-freeze level, a low cooling system is the most common cause of no heat, next check for a kinked heater hose after that the water pump or heater core are suspect. I hope this helps. Take care.

You have aux heater in back, right? There must be hoses going to both front and back heater cores. Look at oem websites like the link below. Chevrolet Venture Hose Heater Hoses and pipes heater 10416869

check to see if there is plenty of antifreeze in radiator , may have a air bubble in system .

Water dripping from your firewall could most likely be your heater core. Most heater core's are located under the passenger side dash.

Check that the heater core is not leaking. It is under the dash. When you look inside the hood against the firewall, there are two hoses going into the cab. Thats where the heater core is located. It could be leaking into the cab inder the dashboard.
