so i guess my hfl module is out for good? when i press on the talk button, nothing happens at all. no beep or anything.. how much would it cost to get a new one and where can i get it?

and earlier the ac was also showing up as red but now it's green.... the AC does have some cool air and keeps the car cool (not cold), but when it's like 100 degrees the car barely stays cool enough... any ideas on what i should check up on regarding the ac? i feel like it should be much cooler.
