Was not sure where to post this so I'll start here. I have been told by several of my buddies that if you are running and high speeds 90-110mph range that you should turn off your AC because the clutch in the compressor cannot keep up. The reason I ask is that on several occasions when I really got cooking on the interstate with the AC on I smelled a funny burning odor. Not horrible just very faint. It does not smell like an electrical burning odor though. Any truth to that....should you turn off the AC at high speeds?
