just in the last week noticed wine sound not from tranny only when run temp control? when drive down rd here it and in side truck? shut system off wine noise stops no resevoir for power steering? thought it was that sound but this 2013 has no reservior container electronic? sounds like power steering noise when low pressure? any suggestion

 

Since the noise is only noticeable when you operate your temperature control, I would suspect the blower motor is the cause of the noise. Being a 2013, what is your mileage? Are you still under the 3/36 warranty? If so, take it in and have it repaired.
