odd whistling noise
first i have a 2003 f-150 4x4 auto with the 4.6,79000kms. it is the xl version with ac. now whats happening lately in this cold weather (-15) when i drive to where ever after the truck is fully warmed up i will hear a odd whistling sound from the dash area every once in a while.this only happens during accereration.i swear its coming out of the vent area right around the controls.could this be a vacume leak at the climate control or just something thats happening because of the cold .? has anybody eles experienced this ? it just started the other day.im sure its not a bearing or pulley. ,but coming right from the climate control area.

I replaced my IACV last week, now I get a whistle
Hello, I clicked on this post because last week I had my IACV replaced to correct my RPM's rolling idle when in Park or neutral. Now I noticed on the highway I hear this whistle coming from the engine compartment seeming like it's in front of dash, and really located where the IACV sits. This really sucks cause I just replaces mine to get this sound. It's a FORD replacement part also. Any ideas? As maybe there's a break-in period?

My truck just started doing this too. the temp is around 5 deg F here. It seems to be louder when the rpms are higher. it does sound like a whistling, but it kinda sounds like something belt driven too. oh well its too cold to screw with it
