When I turn my car off, after being on the road with the AC on, I hear a squealing, chirping sound. It sounds like birds chirping. I finally figured out that it is the two powered cooling fans as they wind down after turning the car off. I can not figure out how to get some silicon or something in there to lubricate the things where they are squeaking. Any ideas on what I can do to quite them down?
Thanks,

Bill
