Blower goes on and off
I have a 2009 Ford F-150 Lariat with dual climate controls.
The blower will go off for a few minutes then start up again. Sometimes it seems like it comes back after I have hit a bump.
When the blower is working I have control of the fan speed. It will go up and down so I am not sure it is the blower resistor as that usually seems to fail wide open and there is no adjustment.
Do you think it could be the blower that needs to be replaced or some other item?
Any input/feedback is appreciated. Thanks.

The motor has brushes in it that ride on the Armature that wear down over time, if you tap the housing it loosens the brushes back onto the armature ( this is why people tap their starters also)
However do you have control at full speed? I think full speed bypasses the resistor. If so I'd replace the resistor looking on Amazon its $23 bucks super cheap.

If problem still persists I bet its blower or loose wiring.
