Ok, I've got a good one. When I run the heater/ac on the lowest fan setting there is a squeaking comming from under the dash that sounds like it could be the fan squeaking, but I don't know where the fan or the blower motor is in our cars. Now, here's another thing, when I'm in gear driving and take it out of gear to stop or something, the squeak gets louder, and I know it has something to do with the heater because when I turn the fan speed up it goes away and when I turn it off it goes away. Has anybody else had this problem? Is it something as simple as getting under the dashboard and spraying some PB Blaster on the blower motor bearing?

Thanks for the help guys!

 

i have this too...

 

I really want to get rid of it.

 

Its most likely your blower motor. Which is located under the dash on the passenger side.

 

Sounds like your bearings in the blower motor are going. I don't think the pb will do the trick but some lithium grease might.
