2010 Platinum A/C issue? Is it the head unit?
 

I have aquired a 2010 f150 platinum with dual climate and navi. The passenger side does not get cold. I have replaced the blend door and still nothing. Check the blend door actuator and it does not seem to be getting any signal from the climate control module. I have read old threads about this but was wondering if putting a new head unit/ navi in the dash would fix this problem. Or is there a different module that controls the climate? Any advice or input would be great.
