A/C killing my hp dramatically

I have a 03 Chevy Trailblazer L6 and when I turn the a/c on it kills the performance of my engine and makes a loud "fan-like" sound, when i say that it kills it I mean like if I was hauling a 3 ton trailer, I hope somebody can help me because I've taken it to many dealerships to try and get it fixed but the are clueless.

Thank you very much

06 Chevy Trailblazer fuse box is overheating and killing the engine.

Hi. I would check the fuse lay out to any fuse card you have for this vehicle. The fuse box should not get that hot but one circuit may be and see if you have a hot fuse. Hot fuse would determine something on that circuit not ok. Good luck.
