Need to learn fix for a/c fan noise coming through speakers when a/c is turned on in vehicle and when a/c fan motor speed is turned up sound mirrors speed of a/c motor
Help
 
Solution
This sounds like a grounding issue. Make sure the grounding strip (connects your engine block to the firewall, often looks like a flat braided cable) is actually connected firmly at both ends.

Good luck.
