my heater blower was working fine and all at once started making a roaring noise on 2007 Dodge Caliber

i turned the blower up on high and it sounded like it blew something loose and was doing fine but every now and then it roars and i can feel the vibration in the steering wheel when it is on high

. Check the blower motor speed control wires at the HVAC control panel on the C2 connector. The Blue wires with colored tracers are the control wires, grounding them one at a time will provide a different speed for each wire. The Black wire is the ground for the blower motor circuit. If jumping the Blue wires to the Black wire one at a time varies the blower motor speed, the HVAC control panel is bad.
