Air Conditioning problem
2002 Saab 9-5 4 cyl Front Wheel Drive Automatic 105000 miles
The airconditioning appears to work just fine. However, there is a vibration (expansion tube?) Under the hood, when I turn the engine off, after running the AC. Can I just live with this without damaging the AC system? Also, can I put some sort of runner ring around this tube to prevent it from hitting against other parts under the hood, thus dampening the vibration?
