This was a quick fix to my 2011 Nissan Frontier truck. The original blower fan went out at 24,000 miles and was replaced with another original Nissan blower fan. At 45,000 miles and almost two years later, I bought a replacement motor from an Amazon store to replace the motor this time. The blower fan resistor was replaced every time the blower fan was replaced and both of the replaced fans could not be turned by hand after they were removed. There was no indication the blower fan resistors had gone bad - just the blower fan motor.
