Need new climate control
 

so I have a 06 Silverado with dual manual climate control. The right side of the unit stopped lighting up so i took the unit apart and it does not seem that you can just replace the bulbs. so questions is do I have to replace with the same manual dual control or can I purchase the dual automatic climate control. it seems that the connections on the back are the same. Thanks in advance for the help.

You cannot just add the control head to get the automatic climate control. There are a bunch of circuits and sensors that are missing.
