DESCRIPTION AND OPERATION
Heating/Defrosting
A positive temperature coefficient (PTC) heater is
used to heat the passenger compartment and defrost
the windshield on the Electric Ranger. The PTC
heater uses a two-stage electrical resistance heater
that operates on high-voltage direct current (DC).
At temperatures above 4°C (40°F), the first stage of
the PTC heater will operate to heat the passenger
compartment. At temperatures below 4° (40°F), both
stages of the PTC heater will operate.
The PTC heater is located in the standard Ranger
heater core location, and high-voltage DC is fed to
the PTC heater by the PTC switching module. The
PTC heater is equipped with an overtemperature
sensor, and the air that is circulated through the
heater is filtered through an climate control filter to
prevent possible ignition of dirt or dust build-up on
the heater. The heater will maintain the passenger
compartment at a maximum of 26.5°C (85°F) in
order to conserve traction battery power.
Heating/Defrosting —Postal Ranger
EV
A positive temperature coefficient (PTC) heater is
used to heat the passenger compartment and defrost

heater uses a two-stage electrical resistance heater
that operates on high-voltage direct current (DC).
At temperatures above 4°C (40°F), the first stage of
the PTC heater will operate to heat the passenger

The PTC heater is located in the standard Ranger
heater core assembly located on the LH side of the
dash panel. High-voltage DC is fed to the PTC
heater by the PTC switching module. The PTC
heater is equipped with an overtemperature sensor,
and the air that is circulated through the heater is
filtered through an unique climate control filter to
prevent possible ignition of dirt or dust build-up on
the heater. The heater will maintain the passenger
compartment at a maximum of 26.5°C (85°F) in
order to conserve traction battery power.
The Postal Ranger EV has an unique feature called
a Pre-Heat Function. The pre-heat function allows
for heating/defrosting while the vehicle is in the
KEY-OFF position to help conserve battery energy.
This feature will operate when the vehicle is
connected to the charging station and the outside
temperature is 18°C (64°F) or below. The button for
pre-heat is located to the left of the heater controls,
above the recirculation button. To activate, push the
button once. Heating is limited to 30 minutes of
operation per activation. This function will
automatically default the temperature control to full
heat and set the fan speed. The fan speed is
dependent on the temperature inside the vehicle.
Direction of airflow can be controlled using the
mode selector knob. While the pre-heat function is
on, the vehicle will be in recirculation mode. To
turn the pre-heat off, disconnect the vehicle from
the charging station, put the vehicle in the KEY-ON
position or wait until the 30 minutes have passed.
