The blower motor and assembly are located on the left side of the motor and cover some important components that you will want to get access to. Besides removing the assembly to get access to things like the fuel rail you will need to remove it to replace the components and blower. Removal is quick and easy so rather than trying to work around it, simply remove it.

Over the years your car may have been serviced by multiple people including previous owners and this can lead to parts replaced with different size fasteners and hardware. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches. If something is different on your vehicle please let us know and share your info to help other users. If you have any questions or comments or even a different procedure you would like to share please leave it below and please leave your vehicle information.

The blower motor assembly is located on the left side of the engine (red arrow).
