Hello! When driving and I turn on AC -upon acceleration, I hear a high-pitched sound. When I let my foot up off gas pedal the sound goes away. If AC isn't on, I don't hear sound. I did have my AC recharged (it was low) about 2 months ago. Ideas? Please let me know. Somewhere to start, ect.

Many Thanks to all who contribute - You are the best!

 

sounds to me like a bearing may be shot in the compressor where the belt turns it. does it cause any problems other then just a whining noise?

 

[align=center]Hi Janet[/align][align=center][/align][align=center]Sorry to read about your problem with your Monte[/align][align=center][/align][align=center]Its difficult to give an exact sollution to your problem[/align][align=center]from just reading your post[/align][align=center][/align][align=center]It may be as simple as a bad tensioner for the a/c/ belt orit could be a bad compressor or clutch fan[/align][align=center][/align][align=center]The noise you are hearingcould be abelt tensioner hitting the transmission cooler lines. The reed valves in the ac compressor if broken can cause the fliud to pulse through the compressor and make the belt jump. The only way to fix is to replace the compressorifits not a belt or tensioner problem.[/align][align=center][/align][align=center]I hope that one of our MCF members has more suggestions[/align][align=center]sollutions for you[/align][align=center][/align][align=center]I would suggest taking it to a trusted mechanic and[/align][align=center]getting a checked and an estimate on repairs[/align][align=center][/align][align=center]Wish you Good Luck and Cool Air[/align]

 

Thank you both. I'll have checked out Mon or Tues - will let you know outcome. I had a feeling it was compressor. I turned on today and all I got was hot air.
