Default installed CB, now strange motor noise

I installed a cobra 75. I pulled the front console and installed the little electronics box there. I connected power to the rear windshield power switch.
Connected red from CB to the blue wire on the wiper swith and ground to the black wire. Everything works - BUT -, when I key the mic, there is a small whinny motor sound from the engine. IT IS NOT the wiper water pump.
It is real quiet, I cannot hear it when the engine is running. IT is a high rpm motor. It is coming from the block, on the exhaust side of the engine.
I have a feeling some of you are going to tell me I'm crazy or say its the wiper pump you idiaot! ITS NOT!
The hummer idles fine when I key.
I have not driven it yet to see what happens. Kind of afraid to.

Dan

No. The noise is not coming from the cb speaker.
The noise is coming from the engine.
And there was no noise when I had it hooked up for two weeks using power from the cigarette plug.

There is a spare power wire marked acc on the driver side right by the door open light. Its steady 12volts. Connect to that rather than wiper source.

I thought of that but I did not want a constant source.
I am more curious about what the motor? is.

Try a different ground. I suspect your getting a feedback voltage to the washer pump which is energizing the pump, but not with enough voltage to pump the fluid.

Agreed, I believe you can filter that noise out. And, don't be afraid to drive it.
