Can someone post a pic of the backside of their Old Air Product control unit? Would like to see if the 2 split blue wires are connected to anything.

My ride went in for full repaint in April with an 2 month old and working heat/AC unit and got it back but heat/AC wasn’t working.I found grounds disconnected and that resolved the heater issue and my AC compressor kicks on now as well but no cold air. I noticed now there are 2 blue wires not attached to anything in the back of the control unit. Can’t think of anything else other than maybe Freon leaked out…

Edit: Nevermind found out the blue wires are optional for lighting on the control panel
