My climate control panel has the auto choice on the A/C knob and a sink option on the right side temperature adjuster.
The blower knob is in the middle. No power to anything on the control panel.
Any help will be appreciated.

Hello,
Sounds like your fuses are good. At this point it sounds like a possible HVAC controller. To be sure you can remove the controller and verify proper power and ground to the HVAC unit before replacing. I have attached the procedure to remove the HVAC controller, and info display module and what wires to check. The controller is different then the info display module which in your case is not working. Remove the controller behind glove box area and Check pin 1 at the HVAC controller connector x1 for battery voltage. If that checks good remove to info display module and check for battery voltage at connector x2 and check for battery voltage on pin 1. Also check for ground at pin 10 same connector the black wire. If you have good battery voltages on these checks It sounds like you may need a info display module. Could be something else please let me know what you find on your voltage checks.
Thanks

If you have power and ground the HVAC controller has gone bad. Here are the complete HVAC wiring diagrams so you can see how the system works and how to replace the HVAC controller as well.
