Need help, any idea what it can be? No power to Climate control unit

[Cluelessmk7]

Need help, 2015 Mk7 Golf R after installing a few parts into my car, FMIC, discharge pipe I noticed my whole climate control unit/HVAC unit not getting power ( A/C, heated seats, windshield defroster) literally no power to that unit at all, checked fuses & everything seems to check out not sure how to go about this or what else to do besides going to A/C shops & getting told they can’t find anything, figured this is an electrical issue & seriously want to get it fixed, any pointers or things I should try doing? Thanks in advance!
