Purchased a discovery V recently and am loving it so far. I have a damaged rear climate vent, on the overhead ceiling blower unit for the second row passengers. I bought this replacement (attached pics) I am unable to remove it easily from the ceiling and obviously don’t wont to damage anything further or the headliner. My only clue is from the new unit I ordered it almost looks like it is screwed in.I Haven’t been able to find anything relevant online about this. Does anyone have experience removing or replacing this before? Any Help would be appreciated. Thanks!
