That is normal, the other fan is for when you have the are conditioning on.

Are both fans suppose to go on when you turn your ac on?

ya when i turn my ac on on my 92 gs both fans go on and stay on. is it normal for them to stay on untill u turn the ac off???

This info I know to be correct for the '92:

For the A/C, the fans come on together whenever the compressor is running.
There is a resistor so that the fans (when both are on) can be either low or high
speed. The A/C control electronics decides if it wants low or high. If the
radiator coolant is getting hot, this will force them to high speed, regardless
of what the A/C electronics is asking for.

In moderate weather, the compressor should cycle on and off. When you've
got the A/C turned on inside the car, but the compressor is cycled off, the fans
stop (if the radiator is hot, then just the 1 fan keeps running). I have an
indicator light for my A/C compressor, and on many days, the percentage
of time the compressor spends actually running is surprisingly small.

The fans can't ever use low speed when the compressor is off. In that case,
it's just the passenger-side fan, and it just comes on at high speed when the
radiator coolant is hot.

The one circled in black...

BUZZZZ!!!!! yes Tim, i'd like to buy a vowel.... hehe!

anyways, where do the wires to that thing go? how many are there? what color? is that off of a 4G63? n/t with a turbo right? give me some more info to work with, we'll try to figure things out!
maybe tomorrow i can solve the puzzle.

oh yeah, one more thing. next time circle it with a color that would stand out a little bit more.

ummmmmm... i see a big fan with a metal thingy in the middle and 2 wiring harness :laugh:

distributor?

It's a big mother resistor. It's how they control the speed of the condensor fan. Somehow, for many years, they've used resistors to control the speed of such things as heater blowers and radiator fans. Beats the hell out of me, I guess it's cheap and effective enough. Your heater blower has a resistor pack in the airstream that gives you the various speeds. In my experience, I've only run across continuously-variable speed fans in Datsun Z cars (although by now they must be all over the place).

Now then, the speeds on your windshield wiper motor are varied by having one pair of the brushes on the armature off of 180° apart, at 150° or so.

Just bizarre.

If you look just to the left of the cirlced black piece, there is a 4-wire harness, which you can see the inside of. Two of the wires on that harness go to the fan motor and the other two go to that box thing that Defiant named a resistor. My question is, do I need the resistor? I am actually using 2 AC fans attached to the turbo rad (for extra room) and wiring it up to be put on an incockpit switch controlled by an automotive relay. I don't need to control the speed.

Can I just trash this box piece?

Yes, it'll give you continuous full-speed. So the fan motor will be junk in..... about ten years, probably.

Well the fan will only come on with my switch so...
I give it 20 years.

SEE YOU LATER BOX.

So witch two wires go to the resitor and which to the fan?
