My blowers won't go on switch won't light up either.Both breakers are good anyone know where the motors are so I can see if they are getting power?

In the rear corners of the engine compartment...I think.

Could be the rocker switch if it does not light up

Was thinking that, have not looked at it yet.Was putting new exhaust on last weekend.With the switch not lighting up there is either no power at the switch or its bad.Doubt both fans could go bad at the same time.

No, You are right on both motors, I had to relace a few rockers on my 312, They do seem to go from time to time, I would switch wires with another rocker to see if they come on to rule out that switch

You guys got me all excited! I thought someone was experimenting with superchargers!

I thought of that after I posted.
