Climate control system completely stopped working. No heat, no A/C, no fan for front and rear vents, and control panel display is not on at all. I checked fuses and there are no issues. Could a faulty final stage unit be the cause for all of these problems, including the control panel display not working?

Hello,

This does sounds like the control head, but to be sure let's check the power and grounds of the unit. Here are a guide and the wiring diagrams so you can confirm the failure:

I had this problem, it was the control head. I got a used one for $150.00 works great.
