Ok I have a question if I by pass the plug on ac blower motor what will happen is it unsafe ?

 

If you are going to eliminate the plug and connect the wires directly to each other then it will not be unsafe if you make good connections.

 

Not sure if I understand your question fully, but if you mean just applying 12v straight to the motor, then the motor will be a full speed... and yes you can do that to check the function of the blower motor....

 

What exactly are you trying to accomplish. What issues are you having. like above, yeah if you just want to connect blower motor directly to eliminate plug then there is no harm as long as there are no other wires(controls) on the plug which you may have to splice them all in.
