[s-cars] Squealing chipmunks (in dash vent)

[mtgadbois at aol.com]

 Bob,

I hate to tell you this but it's probably not the little fan.  I asked a similar question to this list about 2 or 3 months.  The little fan is a real pain to replace but I did it.  I owe you a write up and have done about 1/2 of it but again that's probably not the problem.  After replacing the little fan I took a 2 hour trip to Iowa.  About an hour into the trip the squeal came back.  I did a bit more research on the internet and came across a posting that said that the noise was due to the brushes being nearly worn out in the a/c blower fan.  I may go down this path but I've got a feeling that it would be a major pain to get at the blower fan.  I may just turn up the radio.

Hi Y'all,

My urS6 has started to develop an annoying squeal which sounds like 
it comes from the little cabin air temperature sensor under the 
little grille to the right center of the dash.  The chipmunks go to 
sleep if I stop the HVAC blower.  I suspect that if I could get some 
decent lubrication in there that my problem would be solved.

So what's the trick?  Just spray some Kroil into the grille opening 
and hope it gets to where it needs to be?  Or pull the entire dash to 
get to the chipmunk nest?  Or?
