I have a 1997 Z3 w/ 60K, and on a hot day, when I start her up, she beeeeeeeeps at me until the interor cools down via blasting the air conditioning. I think it is probably wiring somewhere, but is this something that is common? If anyone out there knows where to look, or some kind of fix, I would be grateful. I am just afraid of the pricetag from a dealer for anything electrical.
