Hey Chris,

Can I ask if the air not blowing is the problem or the air is blowing but not cold? Please let me know so we can head in the right direction to fix it. :)

Okay, most of the time it will be the lower motor but as should check the fuse #24 which is under the fuse panel.

Here is a guide that can help and the fuse location in the diagrams below:

Okay good, let's use this guide to check for power and ground at the blower motor, chances are the blower motor has gone bad but this will confirm the problem.

Yep, this was most likely the blower motor burning up, does the fan motor not wok at all speeds?
