Hey guys I have a 2014 mustang 5.0 and I been hearing some whining noise coming from the cabin. I took it to a mechanic but was too busy to fix it but told me it might be one of the pulleys. Not sure which one but before he works on my car do you guys know if it’s a pulley, belt or even a water pump? Just want to make sure before the mechanic tries to tell me it’s more then just a simple fix. Thanks guys! Car sometimes makes the noise but it does it more when I accelerate and let go of the gas.
