What turns the aux fan on?
 

I was wondering, cause the damn thing came on on me the other day. I hooked up the battery, to find suitable power/ign/light wires for my gauges, and the damn thing was on. I unplugged it, and a light came on in the idiot cluster. Just wondering what turns it on.

The car had no coolant in it and hasnt been run yet.

i have been meaning to start a thread about it! im wondering as well.. :scratch:

There is a sensor up by the filler neck, if you unplug it the fan will stay on all the time.

green wire? i have the wire/plug, but nothing to connect it to...

funny you mention that, today i was looking at an automatic 86 GXL, and it had that wire plugged into something on the filler neck that my filler neck does NOT have.. :confused:

The A/C turns it on. Also, if your temp gets to something like 208º

Im wiring mine to come on with my main efan. Cant hurt, right? :)

theres an idea.. lol.. :)

how you gonna make it not tamper with the gauge light?

I wonder if my A/C compressor not being is has something to do with it. Maybe the wire is grounding somewhere.
