2003 Dodge Ram Van 3500 Q&A

2003 Dodge Ram Van 3500 Question: Hi pitched whine from AC?

I hear a hi pitched whine when I accelerate WITH THE AIR CONDITIONING ON, then rises in pitch and fades in volume. It stops when I turn AC off. What are the most likely culprits? Thanks a million -

This sounds to me like it may be a worn belt. That's be the first thing to check. -
