so in summer when id turn on the AC occasionally it'd make a high pitched noise, almost like a bird getting strangled.. and it would come from the air vents. then as winter came it continued with the heat. its gotten to the point where it happens ALL the time, and its super loud and obnoxious. it has a deeper tone to it not tho but still goes right thru ya. also when it is making that noise it doesnt pump out heat. its also started to make another noise i cant even really describe its this low pitched yet loud rumble/groan or something. like i said its hard to describe. also with the rumble thing, i can feel it in the pedals. any ideas on what went wrong and what needs to be replaced?
