97 540i A/C Noise

i get this werid noise like a fan is hitting against something when I first turn on my A/C. But it doesn't look to be a raditor or a/c fan. This happens for just a few seconds after turning it on. Also happens at times depending on egine rev. The higher I rev the louder or faster the "fan hitting noise" is.

The A/C blows cold at times too. If the car is in motion with the engine revs up, theres no problem. But if im at a red light, after a few seconds....warmer air is coming through the vents.

Can anyone PLEASE HELP or HAVE ANY SUGGESTIONS?

DAMN TEXAS HEAT ISN'T HELPING

PS: after examing the noise it seems to come from the lower left front of the E39 540i engine.

It sounds like your having a compressor issue. Only the compressor would rev up or down as the engine does. Check to make sure when the clutch on the comp. engages its not hitting anthing tha might be loose around it. If you can see anything externally then your problem is internal but it would the compressor
