Ac blower not coming on

Sounds like a bad blower motor resistor.

Or bad blower switch

If the resistor goes, would it take out all the speeds?

Usually High is the only speed, the resistor controls the low speeds, but it depends on the manufacturer.

So how dose one fix it or can it be motor electric bushes

Make sure the a/c fuse and relay is good and the clutch cycles when you turn air on. If all looks good system may need a charge.
