How to Change the Blower Motor on an '05 Escalade

Iskandar Blogger 11:28 PM

The blower motor in your '05 Escalade blows the heat emitted from the heater core throughout the interior of the truck. Other than electrical failure, the blower motor should typically last the life of the Escalade. That's not to say that it cannot be damaged, because individual use differs. Operating the blower motor on high every time you turn it on wears down the motor, eventually rendering it inoperable. You can remove the defective blower motor on the Escalade at home in 30 minutes with a few basic tools.

Instructions

    1

    Open the front passenger-side door of your Escalade and position yourself so that you're able to see under the dashboard. Just under the glove box, back against the firewall, you should see a black cover held in place by three bolts. This is the blower motor's protective cover.

    2

    Remove the three bolts holding the cover in place with a socket wrench. Pull the cover away from its mounting position and set it and the three screws on the driver's seat.

    3

    Unplug the power wiring harness from the blower motor. Observe the blower motor's position and the way it is mounted inside the HVAC housing. If you look on the left of the blower motor's base plate, you should see a small retaining tab.

    4

    Pull down on the retaining tab with one hand. Grasp the top of the blower motor with your other hand and turn the entire blower motor counterclockwise. When the blower motor unlocks from the HVAC housing, let the tab go and lower the blower down from its mounting position.

    5

    Install the new blower motor just as you removed the old blower. Lift the new blower motor into position, pull the retaining tab down and rotate the blower motor clockwise until it stops, then let go of the tab.

    6

    Plug the blower motor's power wiring harness back up to it. Reattach the blower motor's cover with the bolts. Thread each of the three bolts by hand to ensure they thread properly. Set your 1/4-inch drive torque wrench to 14 inch-lbs. and tighten the bolts.

    7

    Start the Escalade to ensure the blower motor is working properly. Check the heat and air conditioning circulation at all of the truck's vents.
