Randy that is fine, I will check this email later. I appreciate your help.
Just to clarify if you have the mode switch turned to the defrost mode the AC light will light and stay on. You cannot turn this switch off when the mode lever is in the defrost mode. Make sure the mode is on vent or feet then see if the light on the AC switch turns on and off normally. I have done multiple searches for air-conditioning or heater problems with the control panel and have found none. I want to make sure that you are aware that the AC switch will not turn off if the defrost or is that defrost mode.
It is unlikely a fuse or power input if even one of the buttons are working the power supply is normal. You are probably looking at the control panel to be replaced. If you want to post the VIN I can run any inquiry on the panel to see if there are any issues with it. I checked all known service bulletins and have found no particular issues so far. I have never had to replace one either. This is not a common problem. Let me know how you would like to proceed.
I cannot get to my vehicle until later today, therefore, I don't have the VIN #. I will have to take it in. Thanks!
If you can get then let me know. There is a website I can direct you to where you can save some money on the factory part is it works out that the control unit is defective.
