I have a flex-a-flite fan I got my A/C compressor hooked up to my E-fan and know my fan doesn't turn on at all. The fuse is fine I unhooked my switch still doesn't work, unhooked the A/C still nothing. I even unhooked it from the battery the lights turn off put it back on all 3 lights go on even tho just the fan is hooked up not switch or A/C wtf is wrong. Also my fan was installed about 3/4 of a year ago just got my A/C hooked up last week it worked till a couple days ago. HELP!!!!!

 

this is a bit confusing.....and why did you hook it to the a/c? should be on its own circuit...

 

Ok First.....are you hard wired or are you using a controller? Second -have you tested the fan by running the 2 leads from the fan directly to your battery?

If you are using a controller there is an option to hook one wire ( Mine was Green) coming from the controller going to the compressor . This wire Makes your fan come on as soon as you turn your AC on regardless of engine temp.

If your Fan Worked Before and Just Quit, and you run power direct through the fan and that works, then I would Say you have a faulty Relay....just pick one up for a couple bucks and try swapping them out , just make sure it's the same.

 

Ok srry for the confusion I'm running it with a relay, it was suppose to be ran with the A/C compressor, it worked when I first put it in. Tested it with the A/C on when the truck was cold it turned on and everything how it was suppose to. Then my starter went out and I pulled my battery out to get it tested to make sure that was fine. Battery was fine and I replaced the starter and know it don't work.

 

Test It and post the results.

 

Ill get back to you 2morrow its 11 pm in my neck of the woods lol.

 

OK I tried running from fan directly to battery and nothing. I tested both fans, so does this mean that my fans are shot already? Thank god its getting to be cold in WI or I would really be screwed.

 

Do you have the temp sensor hooked up inline?

 

Check for continuity in the fans and down the wires you are using. The little beeping sound thing on a multimeter. You should be able to put one lead on a neg and positive wire and get a beep thru the fan as there's just copper coiling thru the fan, it should pass current all the way thru it. If the fan won't beep, it's dead.

Also, if you used any crimps or quick connects/disconnects, make sure you check them for corrosion and solid contact.

If you are running the flex a lite controller, it has a relay in the controller, as well as that big fuse that goes between the battery and controller. Make sure you see the red light that shows it's getting power.

E-fan connections take a pretty severe beating being near all the dirt, rain, road grime, etc. I usually use crimp connectors with heat adhesive, then use heat shrink wrap over those, then wrap them in electrical tape. I know that sounds excessive, but after having the connections fail on me a few times, I don't screw around with it anymore, I go for broke.

Mount the fan where you want it, measure the wires by running it wherever it needs to go and then add a couple inches, cut the wires to length, and build the harness outside of the truck.

 

I've only heard of one guy of all the guys I know with a Flex-a-Lite have it go out on him. Flex-a-Lite replaced it for only the cost of shipping.

So with it being less than a year old, I'd go that route if connecting it directly to a power source didn't even make it spin.

Although I'd not volunteer the fact that you have been "messing" with the wiring, A/C connection, starter & battery just before it quit...
