Default HVAC problems?!?!

Okay so I had just taken out my hvac bcs i planned on removing my dash but plans changed as I put my hvac back in none of my lights on the hvac will light up, and itll switch from hot to cold and the fan speed will change but when I turn the control to go from off to ac to fan to defroster nothing changes it just blows out the defroster and turns off thats it...it used to make air sucking noises when I would turn it and it no longer does that and there is no resistance when turning the **** anymore...please help

well I drove it today w/ the hvac panel off and I could def hear the back part to the far right **** sucking in air so I would assume my vacuum hoses are still connected and what would cause the lights to not work on the panel..i never did anything to them but take them out of the panel
