Hello, thank you for your help.
The fan does not seem to be working on any setting. When you turn the AC on and put your hand on the vent, you can tell that it is on because it’s cold. there’s just no fan to push the air.

Is this a fan issue or possibly a resistor?

What would be the procedure?

Hi,

In most cases, a faulty resistor will still work on high speed. If you are not getting the blower motor to run at all, it could be a fuse or relay in the integrated power distribution module under the hood (fuse box).

Do me a favor. Check fuse 42 to make sure it is good. Confirm there is power to it as well. Here is a link you may find helpful:

If that is good, locate the blower relay in the same fuse box and switch it with a different one in the box having the same part number to see if it is a faulty relay.

I attached a couple of pics below to help you locate the fuse and relay. Let me know what you find or if you have questions.

Take care,

joe

See pics below.

Hey Joe, I just checked the fuse and relay, and both are good and are receiving power.

Yep, lets move onto the blower motor which is a common failure. Here is a guide to help test for power and ground and I have included the blower motor location as well.

It looks like the blower motor is hard to get to, but the wires are easy so I would use those for the testing. Check out the images (below). Please let us know what happens.
