Hello All.

Do have a question for those that are mechanically savy. Only when I have my A/C on, and get to where im going and turn the truck off I get a whistle type sound that I hear. But when the A/C is not turned on I do not hear that whistle type sound. Any help would be great.

Thank You

That is just the freon in the lines going through the expansion valve until the line pressure lowers. It's fine.

 

Thank you very much I am glad its not something more. It makes since now to me.
