I am new here and this is first post. I have just taken my 2012 Express in for the 16,000 look at with a few minor things for them to inspect and one being that the AC was not very cold was told that refrigerant was low but found no leaks now to the problem. I now notice a electrical sounding motor whine coming from underneath the truck some where I can't seem to nail it down. When I turn off the engine it continues to spin down for a while after the engine has stopped. I am sure it is not coming from the AC compressor because it continues to cycle as it should.
