i'm having a slight heater prob... more like an annoyance, really. the blower works good and strong, but sometimes it makes a sound like when you suck out of a straw, and there's a hole in it... know what i mean? at the time it still blows nice and hot.
it seems to happen when it's really cold outside (like below 20F) otherwise on a warmer day it's not there. could it be a check valve? which one likely? or is the heater going end up? where do i findthe vaccum line(s) in the engine compartment? i looked in my bentley but there's not much i can do short of taking the car apart, which i don't have time to do unless this is narrowed down. thanks!!
