I bought a used 2010 with 33k. When its warm there is no issue. When outside temp is below 45 degrees the blower motor whistles at lower fan speeds until its warmed up. I threw an OEM Honda cabin filter in. It even makes the noise when the cabin filter housing is pulled out. I find it hard to believe the bearing would be shot with only 33k. It seems to get even louder at idle. Anyone else had this issue?

 

Try bringing it in for warranty issue. Since you should still be covered under the original warranty.

 

Yeah I tried searching and couldn't come up with anything. I might tear in to it tomorrow and see if I can find the culprit. If it is the motor , I'll take it to the dealer so they can rip the dash apart as I cant see any way it would come out from the bottom.

... even though as I have discovered lately the process of removing the blower motor isn't that simple. If the dealer bills for 2 hours, plus the part and you are looking at around $300.

 

It's probably the blower motor. I haven't had this problem on the TL but on my previous MDX's a 2005 and 2008 the blower motor was making the whistling noise you described and was replaced under warranty.

Not sure where it is on the TL but on the MDX I was told it was under the passenger side of the dash and wasn't a big deal to replace.

 

It also can be the propeller shaft I'm going thru the kettle/whistle noise on the front right still doing research
