My A/C fan motor sounds like there's something caught in it. It's making a buzzing sound when in speeds 3 and 4. What's the easiest way to access the fan to check it?

Hello,

The blower motor is mounted on the passenger side firewall. You will have to access it from under the hood (see diagrams).
The replacement procedure is straight forward.
To get the fan out you will have to disconnect the wire harness then take off the mounting bolts. The fan will pull out.

I included the procedure for both the automatic and manual climate control blower motors.

Please let me know of any questions.
Thank you.
