New to me truck. 2014 6.2, 4X4. 61K. Now this may be completely normal but that is why I am asking. I have had the truck for going on a month now. Since the hot weather has kicked in I have noticed that when the truck sits out in the sun for a while, when I start it up there is a new noise. It doesn't kick in right away. It may take a minute. It sounds like an old compressor kicking on. The truck gets considerably louder. It seems that once the AC has cooled the interior down and the engine gets up to operating temp it kicks off. It does not come back until the truck has sat for a while. The last two days have been much more mild and the old compressor noise has not happened. When I say old compressor, it doesn't sound rough. Just louder. Normal? Vacuum leak?
The AC blows cold and strong like it should.
Thanks,
