Blower motor

The blower motor is accessed from under the dash on the passenger side.

I take that back. I saw Ram 1500 and thought it was pick up. I see now it is a van.

Here are the instructions from the service manual.

FRONT BLOWER MOTOR

REMOVAL

Disconnect and isolate the battery negative cable.
Remove the upper half of the radiator fan shroud.

Front Blower Motor Remove/Install

Unplug the wire harness connector from the blower motor.
Remove the blower motor cooling tube from the nipple on the blower housing cover below the blower motor.
Remove the three screws that secure the blower motor mounting plate to the blower housing cover.
Remove the blower motor assembly from the blower housing.
If the vehicle is equipped with air conditioning, move the suction and discharge lines as required to remove the blower motor assembly from the engine compartment.

Blower Motor Wheel Remove/Install

Remove the retainer clip from the hub of the blower wheel.
Remove the wheel from the blower motor shaft.

INSTALLATION

Press the hub of the blower wheel onto the blower motor shaft. Be sure the flat on the blower motor shaft is indexed to the flat on the inside of the hub.
Install the retainer clip over the blower wheel hub. The ears of the retainer clip must be indexed over the flats on the blower motor shaft and blower wheel hub.
Apply a small bead of RTV rubber sealant to the blower motor side of the rubber seal and isolator unit. This will help to secure the seal to the blower mounting plate during installation.
Position the rubber seal and isolator unit to the blower motor mounting plate.
Position the blower motor and seal to the three mounting bosses on the blower housing cover and press the isolators over the mounting bosses.
Secure the blower motor mounting plate to the blower housing cover with the three mounting screws. Tighten the mounting screws to 2.2 Nm (20 in. Lbs.).
Reinstall the blower motor cooling tube to the nipple on the blower housing cover.
Plug in the blower motor wire harness connector.
Reinstall the upper radiator fan shroud.
Connect the battery negative cable.
