Welcome to 2CarPros.

When you say you hear a click, where is it coming from? As far as the rear auxiliary HVAC, there is a fuse designated for the system. I attached a picture of its location. It is in the under hood fuse box. Make sure it is good. Also, are you sure the blower motor isn't bad?

Let me know.

Turns out there’s a big plug under the driver side floor that that has about 10 wires or so and the main wire (big orange wire) has faulty contact. Apparently it’s a common problem. Found that out on another forum. All I did was fix the connection pins inside the plug so there was no play and the contact was secure. Thanks
