A cattle blower is actually an "industrial" type blow dryer for cattle. When cattle are shown in competition, they are washed and then they use the blow dryer on them, otherwise known as a cattle blower.
If the blower isn't working, start with the easy first. Get out owner's manual and find all the fuse locations. Check which fuse controls the blower and then check the fuse.If there is no fuse for the blower, then you need a professional tech to test it. It could be the blower motor, a relay, a blower resistor, the blower switch or the wiring between any two or more of those components.If the blower motor is out in the open, you could try LIGHTLY tapping on it with the handle of a screwdriver. If the blower starts working right as you do that, then you have a bad blower motor.
Fuse is blown.
