Re: whistling '95 Crown Vic
Thanks to everyone with thoughts about the whistle on my car. I kinda
figure I might fix it by turning the stereo up a little bit more. The noise
is definitely coming from outside, not under the dash. I lost a chunk of
the drivers door weatherstrip a few weeks ago - the seat belt thingie got
caught one too many times. The gap is letting a lot of noise get in.
I may clean the IAC just because - I haven't done a thing to it ever! First
things first, tho. I need for the car to make heat. I replaced the t-stat
last week and had heat for a day. I kinda suspect a heater clog. I hope I
can backflush it - I don't have the patience to replace it right now. The
parts sites show a heater control valve but I sure don't see one. Tomorrow
is a day off for me - I guess I'll conduct some experiments. The garage
isn't quite down to freezing, yet.
