So my relay for my blower motor took a **** on me which led to no fan speed selection on my climate control panel. (manual- turn knob style).

Anyway slapped a new relay on the relay "fuse panel" on the passenger side of the engine bay down under the air box. Now when the heater or AC is in the "OFF" position i'm getting a small steady whine under my dash. When I select anything but OFF, it goes away.

Did I get the wrong relay or what?
It was a Duralast I got from Autozone.
