I did a search for this and couldnt find anything so here goes....Just recently, the blower in my dash of my 04 screw has started making a "rattling" noise, like maybe it could be loose? It only did it on level 4 but now has started doing it on 3 and 4. Anyone know whats up? Any info is appreciated, thanks in advance!!

 

Suppose it could be any of many things - but had an occurence on another vehicle where the plastic of the blower impeller failed in the area of the motor shaft - essentially, it partially stripped out. Air was still moving, just sounded gawd-awful.

 

you know what, Whenever I turn my heat or AC on, the blower fan shreaks a little bit, then goes away. Is that the same problem you have?

 

could be a blower motor relay or sensor. Also something could be stuck inside the blower like leaves for instance. I had this happen on another vehicle I had. It sounded just like you described.

 

mine shreaks also but i got used to that it only does that when you first turn it on. the rattling noise wont stop....sounds like the fan itsself is loose. Anyone have any idea how to get to it???

 

have had this same problem and not one answer on this forum

 

JSS - considering this original thread posting is approaching 2 years old - perhaps post it as a new thread?

At any rate, suggest the need to inspect the blower assembly.
