Hello all, just signed up for the forum tonight, I have a 2021 Silverado LT with 2596 miles just got it last May.
There seems to be a high pitch/humming noise only when the AC is on. To best describe it it sounds the same as a power steering pump when it’s low on fluid. The noise increases a bit when i hit the gas.
it goes away if I turn the AC off.
turning the steering wheel has no effect on this whatsoever. The noise can only be heard when parked and the blower being on a low speed.
anyone have suggestions other than taming it to the dealership? It’s a brand new truck I hate the dealership game, as most people I’m constantly busy with work,kids, maybe a little more as I manage a hotel, this is part of the reason why I bought a new truck so I wouldn’t have to deal with repairs or at least as many, and definitely not that soon!
By the way my past truck was a 2010 FORD F-150. R.I.P timing chain broke and even after a rebuid still sounded like crap and whole truck was shaking. Had 230K on the clock.
