Im having an issue with the climate control, I have no defrost or ac / heat. When I push auto on the hvac button the light doesnt illuminate and nothing happens, if I try to activate the climate control from the touch screen nothing happens either. I've tried replacing the whole Bezel with hvac controls attached twice and have had no luck.

I've checked all the fuses related to hvac and blower motor and all seem to be fine.

Are there any suggestions, I keep replacing the hvac unit with other used units since the dealer discontinued the part, I have tried 2 more units But its not solving my issue.

Sure, I can help, lets remove the unit and use a teat light on the red wire which should have power at all times, then turn the key on and check the pink/green wire next to it and it should have power as well, if they both have power check the black wire that is a few pins away for ground which you can do by going over this guide.
