99 Chevy Suburban C1500 AC Hose Assembly Leak? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Your ac lines will not show condensation unless the compressor is engaged. The ac button normally lights up when ac is selected but not always in case you are thinking it's off when it's not lit.
My 03 Tahoe's ac button works backwards. It's lit when the ac is off and not when it's on. I suspect someone has changed the control panel somewhere along the line in mine.
It could be your old control panel was alright but the blend door actuators were at fault. They are small electric motors and do fail.
