No lights on the air control panel. No A/C, no blower, no heater. Checked all fuses and relays.

There are five fuses that run the system I would check them for power and if there are good check the system ground, here is a guide to help you and the wiring diagrams so you can see which fuses to check and how the system works.

If the fuses have power and the ground is good let's replace the HVAC controller. Check out the images (below). Please let us know how it goes.
