sounds like the compresor in dying. an a/c tech can add some oil but it is probly to late. make sure the bolts are tight. then run it till it dyes. good luck

Just lately, my A/C has been making a steady low droning noise. It makes the sound whenever the A/C is on. Whether the compressor is working or coasting makes no difference.

I opened the hood and peered around and the drone eminates from within the engine bay, but I cannot determine the source. I put a mechanic's stethescope on the compressor and it sounds okay. Seems unlikely that the small A/C fan by the radiator could make such a low pitched sound, but I suppose it could.

A/C is running fine. Any ideas?
