Let me know if anyone else here has experienced this...when the heater is on in my car on any of the settings, I hear a whistling noise that sounds like it is coming from under the dash on the passenger side. They "fixed" it once, but I still hear it. It seems to be the worst on settings 2 and 3.
Thanks.

 

its a little man trapped in there.. take away his whistle and he will stop bothering you..

 

It's the Vortech heater fan supercharger...have you experimented with smaller pullies? Adding boost to your heater will give it a very distinctive whine. Maybe if you want a lower tone overall, add a full cat-back exhaust system to your heater, maybe a CAI.

 

u guys are real funny...

i remember something similar like that happened in my car..but it doesn't do that anymore..so i guess problem solved.

 

But why stop there?? Why doesn't he just Stomp that ***** Flat and he won't bother Anyone Anymore!

 

there's a TSB... had mine fixed/replaced and a little rubber 'helmet' but on the fan motor to quiet it down.. doing it again.. so is my pathfinder

 

per say...sounded more like a crinkling paper in the ductwork. Ended up having to replace pieces of the ductwork to make it go away. I was already fired up to use the TSB and they said it not the motor. DOH! Oh well mine got fixed. Without hassle either. New service manager at Kings in Cincy and he treated me right!

 

This is odd because my old 93 Max use to do the same thing, it would come and go. I never took it in to see what it was either.

 

Man it's cold in MD! (as well as the rest of the US)

Our heaters seem so slow. Is there a method in getting us a little
warmer much faster? I used to just wait til the auto climate control kicked in, but that takes so much longer.

Brrrrrrr...
