HVAC issue
 

My wife's 02 TB LT 4wd has the climate control with the screen. The power and controls have been completely cut off to both the back and the front vents. There is HOT air that comes from the front of the dash, but I assume this is just engine heats being let out. I checked all fuses and they're all good. What is my next step? I'm not sure if this has anything to do with it, but it threw the code for the camshaft position sensor and a have yet to replace it. Thanks for any help
