Thanks for the reply Steve. I would go and borrow a vacuum tester today, but for the fact I already know I have a leak. I got lazy yesterday and failed to mention that if my fan is set to blow at head level and I accelerate it switches to blow at my feet. Classic symptom per the FAQ of a split line or failed vacuum servo. I have simply ignored it for years as I only use A/C once or twice per summmer. I am only chasing the "source" of the leak now(because the noise annoys me :). FAQ's point to a split line or servo, just looking to see if anyone else has had a significant whistling with said leak in hopes of pointing me to one location. I am resigned to getting up under there and looking around this weekend. Its a shame you cant do a "smoke test" on the vacuum lines to pinpoint the leak. TTYL.
