For about a year now any time I use the air conditioner or the fan when I make a left or right turn there is a loud clunking noise on the drivers side. If I do not use either there is no sound. It only happens when I use it. Today I took the truck to get looked at and there is an issue with the sterring pump(a service message was posted by cadillac) and that it will need to be replaced. A lot of people are having the same issue.Does this tie in with the sound or is it something else?

It depends on if the noise is coming from the dash HVAC components or from possible Steering or suspension components, We have multiple methods of finding and confirming source of noise with wireless chassis ears, digital bore scopes, electronic stethoscope and more.
