Guide overview

Before you begin

This repair guide covers replacing the BMW 335xi blower motor at home with just a couple of common hand tools. Blower motors can break for many reasons such as old age, failed bearings, or electrical issues. You will start by disconnecting the car battery and then proceed through the glove box to the blower motor. To follow these steps you will need a T20 Torx Screwdriver, a 10mm Socket, and a 3/8” drive ratchet. The guide will take you through 6 steps to remove the blower motor. These same steps will be followed in reverse order to install the new blower motor.

Step 1

Repair step

⌕

Put the passenger seat all the way back to create as much room as possible.
Remove any objects from the floor of the passenger seat so that you have a clean workspace.

Step 2

Remove the panel on the right side of the trunk to expose the battery.

Step 3

Repair step
