The rear works fine, the compressor is working (because cold air comes through the front at highway speeds and the back works). Have replaced the blower and resistor. The blower just does not turn on at all. The fuses I have checked are all fine but may have missed some. I would love to know what all fuses/relays to check and next steps.

Yep, we can help you, so the blower motor is not getting power or ground.

this guide will show you how to test for both:

Here are the ground locations (G200 near the right kick panel) and the blower motor wiring diagrams so you can see how the system works. Make sure the blower fuse #40 is getting power in the under-hood fuse panel.
