Default HVAC control

Hello, I have an 03 and I am having issues with HVAC control. If i turn car on sometimes the control does not come on. If you look at the control while in hand when you turn key off you can see the backlight come on but control does not work. IF I turn key off a couple of times and back on sometimes the control comes on. So i tracked down the relays and fuses and they both are good. I cleaned alot of grounds in engine bay and those are all good. So i thought it was the control board so i sent it off to get it looked at and fixed. I recieved it yesterday and put it back in and still having the same problem. I checked power at relay and fuse and they both have power. Is there a hidden relay somewhere? Do you know what ground is actually for HVAC control? Any suggestion?

My buddy had some similar issues with his and it ended up being his ignition switch. Maybe something else to look at?
