Question about Saturn Vue
It is normal to not have power to the fan switch. The fan in this system has constant power and switched ground via the blower switch. If you do not have ground at the switch, then that is a problem.
Apply ground at pin 1 of the blower switch connector to verify the system works. If it does, you have either a bad switch or a bad ground before the switch. If it does not work you have either a bad fuse, resistor, relay, or blower.
Did you check the HVAC blower fuse that is under the hood? It is a 40A fuse.

Hello there is a HVAC relay and a fuse 10amp located behind the center of the dash. These supply power to the HVAC unit and switch.The 40 amp fuse under the hood is for the blower motor it self.The inside fuse panel is located pass4enger side of the center council The brown wire going into the switch is the power supply that comes from the HVAC relay behind the center of the dash if there is no power there then you will have to trace it back to that relay or the 10amp fuse located in the same fuse box i hope this helped :)
