Put it on the same control circuit for the compressor. Its a low amp circuit anyway.

 

What's the amperage I can go up to with a fan. I know I only need a small one

 

Some folks use the electric fan from a ford taurus. It draws like 30 amps...... on startup. Make sure you run a separate, fused, circuit for the power feed.

 

Wouldn't adding a circuit require a relay as well than?
flexalite makes a small fan rated at 9.2 amps. Would this be ok? Can I install it and use the compressor circuit? It's only an aux fan not a replacement for the metal fan. Which I plan on swapping to a lightweight flex fan anyways.

 

Leave the stock fan as it is. It has that nice clutch on it, so, when you don't need it, it doesn't really draw any power. Plus, it is more effective than a flex fan......

The fan you linked will work fine, keep in mind, it isn't as effective as a pusher, as it is as a puller. (mounting it in front of the condenser pushing air thru it....)

Yes, use a relay, just use the compressor circuit, (either one, control, or power) to control your relay, and it'll work just fine. Still, give it it's own separate power tap. (either from the battery, or, from the big lug the battery cable goes to on the PDC.) Fused, of course.

 

Is there any way to run a line with a fuse from the fuse box? And flex fans not worth it? Good to know. I always thought the lightweight factor would help

 

Why? PDC is under the hood. Fuse block is in the side of the dash..... I don't know if there are any unused spots in the PDC, depends on what options you have on your truck..... Also, you really don't want to add that significant of a load to any of the existing fuses...... chance of melting wires there..... they are minimally sized in any event. (cheaper)

Eliminating the fan entirely does seem to make a difference....... don't know if it is an actual difference, or, just a placebo though.

 

I think I have spots. The truck doesn't have to much in it. It's got a relay space open I think and maybe a fuse under the hood
I did mean the PDC as you call it. Sorry

 

Is it worth the money to eliminate the fan and buy an electric fan? Idk what all it takes to run a larger electric fan

 

Not really. More a convenience factor than anything else. You don't really get much of an improvement in fuel economy..... 1 mpg would be the BEST you could expect..... Trouble is, good electric fan kits run north of 400 bucks...... would take LONG time to recover your investment. Bit snappier throttle response..... better a/c performance, that's about it.

If you can get your hands on the right connectors, and such, shouldn't be too much trouble to wire one in then.
