The right way is also the easy way.

Apparently the fan switch for a Buick GN is common and cheap, and turns on at a fairly low temperature.

Get a relay and the relay connector off of another thirdgen. (just cut the connector off with enough wiring to solder to) That will also make it easy, because the 4 wires already there will guide you in which wires need to go to which wire on the connector.

You need four wires to the relay:

One small wire feeds the Relay with ignition 12V. You can likely get this from an empty single terminal on the fuse panel. Need a 20A fuse in the wire from the fuse panel to the relay IIRC.

Other small wire goes to the fan switch, which should have one terminal on it.

One large wire comes straight from the battery to the relay.

Other large wire goes from the relay to the 12V on the fan.

Other wire on the fan itself goes to ground.

That is a very simple setup, and will work perfectly. Running the fan constantly, from others experience, apparently leads to fried fan motors.

You can wire that up in 30 minutes if you have the right tools, and don't feel like routing it through loom.
