Wire aux fan clutch to electronic fan switch?
I've heard of people wiring their two fans together so they run together all the time. If one is switched on the other comes on with it. Is this not smart? I am wanting to do this to aid my A/C this summer. It's becomming a scorcher this summer!!
If this isn't a bad idea, do I just jumper the two fan switches together to make this possible?

If you want to do it, add a relay to power the fan that will get spliced to the other fan.
I takes the load off the circuit that will be running, now, two fans. |

What about finding the current relay that controls the electric fan and put the aux fan to it?

The wire and relay at present were designed to power one new fan. Old fan, old wire, and questionable connections introduced to more load via second fan brings questionable performance and possible hazards.
It is a four wire installation with a new relay. |

190D22,
I have heard of people jumping the switch on the a/c drier so the electric aux fan runs all the time or bypassing the resistor and connecting the two wires directly so the aux fan runs on high speed instead of low with the a/c but never anyone trying to run the main electromagnetic fan on the engine with it. I think the main fan would have little if any effect at all in helping cool the a/c condenser anyway, this is what the aux fan is for. Both fans are designed run at the same time at (main fan & high speed aux fan) at 100 C on your car already. Chris
