The front AC unit will not blow at all. The rear unit seems to be blowing and working fine. The front unit will not blow hot or cold air. It just went out all of the sudden while I was driving. I turned down the rear AC fan using the front control on the dash and then the front blower just stopped. Do I need to replace the blower? Could it be something else?

More than likely if the blower is not working at all then the issue is either the fuse/relay or the blower motor has failed.

The way to find out is to check the power at the motor. If you have voltage at the motor with it turned on, then the motor is the issue.

Here are a couple guides that will help with this:

Please see the wiring diagram below and let me know if you have other questions. Thanks
