I get a massive vaccum leak when i turn my a/c on or when the heater is set to defrost the front windshield. My blower only works on full blast, but I have a new blower motor here. I hear a vaccum leak come from the passanger glove box. Im not exactly sure what it is, Im going to take the whole crash pad out and replace the blower motor and take the evaporator apart and check if leaves or somethin got inside. Anyone else have this problem or know a solution?
