anyone elses efan suck?
Ok so I put on my efan today... yay.... I love how smooth my truck idles now and the annoying whuuur that's gone..
But, upon doing the install, I found a few kinks... If I've stopped for a few minutes..., and the fan is on, and my AC is on, my ac quits working, and begins to blow warmer air.. Once I get moving again, it cools back down. Stopping at a traiifc light I noticed this. Brief stops don't produce this, but longer ones do.
What can I do to correct this? Will this damage my a/c?
Also, my tranny temp runs a bit higher than it used to... It's running about 205 after 30 minutes or so of good hard driving. It usually ran about 185-190. Again, is this bad? This can probably be fixed with a bigger cooler up front...
I am considering putting the stock fan back on. I love my efan... but I love my truck's health more..

If you are triggering the fan from the compressor clutch, the AC preformance will fade at idle in hot weather. The electric fan just does not cool the condenser enough when it is only on part of the time.
I had to trigger mine from the AC-enable wire to make it run constantly whenever AC is allowed by the mode selector switch. The color code is solid purple and it can be found behind the HVAC control panel or in the engine harness going to the PCM.

My controller refuses to turn off. It turns on as soon as I start the truck and doesn't stop until I turn the truck off. I've contacted Bob via email and pm. No word back from him whether or not I'm getting a new controller...My a/c is always cold, lol. But then again, so is my engine. It stays about 1/8" below normal.

There's something definetly wrong if your AC is getting warmer at stoplights. It should be colder than normal. That would lead me to believe the fan is cutting off....for whatever reason.
My AC is CONSIDERABLY cooler now with the e-fan, as well as lower engine temps. However, I have noticed a sizeable increase in my tranny temps while in city driving. I assume this is because the e-fan pulls air through a more concentrated area than the stock mechanical fan, therefore, not pulling as much air across the tranny cooler. I'm still debating on what I want to do about it.

Someone give me a dunce hat....
I popped the hood and flipped on the fan via my switch I rigged up, without the engine running... I dropped a recipt (only thing i had) into the engine bay, and the fan SUCKED it up to it...
My fan was wired backwards... LOL... I swapped the connectors, pulled on the fan, and LOADS of air flooded into the engine... BA-DOW!
Thanks guys... I guess I'll have to chalk this up to plain ol' stupidity...

You probably didnt need to kill the receipt. haha... but if you put your hand by the grill and feel air blowing out on it, it's backwards or wired backwards. Mine was like that initially and with the ProForm I just had to reverse the GRN and BLK wires. The blade wasn't reversible but the polarity is.

I've sat through entire 1 hour lunch breaks and it's been fine the whole time. I did however keep the stock shroud if that helps any.
With my truck, when the A/C is off, the fan is off most of the time except it will come on intermittently when the truck is stopped and the rad temp creeps up. That's why I have an A/C issue when idling at a stop if I use the compressor to trigger the fan. Using the purple A/C-enabled wire keeps the fan running constantly when the A/C is on just like yours does.

sorry about the hijacking of the thread,,

You do realize that your 2.3L has both a belt-driven fan AND an electric fan already, right?

The temp sensor on mine is totally non-functional for some reason. However, that aside, I will definately agree that the AC works best with the fan staying on via the purple demand wire behind the HVAC panel. I tried the compressor clutch and it was a waste. Also, the only time the coolant temp is ever warm enough to even require the fan is if I sit at idle for more than 10 minutes.

I have no clue what you guys are talking about here??? The compressor wire turns on the Electric fan when the compressor is running..right?
Whats the purple wire do?, keep the fan on anytime the A/C is in the ON position even when the compressor is off?
Well boys & girls since I was an A/C mechanic(big stuff
) & also installed, troubleshot & repaired automotive A/C's when I was a mechanic when the compressor is not running its not going to remove heat other than the evap. coils are still cold so the interior fan will blow air over it & remove some heat for a very short time. The refrig. process has stopped when the Compressor is not running. When the compressor is running then the condensor comes into play & thats when you need the electric fan to run so it will remove heat from the condensor by pulling air across it. Now when the compressor comes on & if the Electric fan is always running it will start removing heat a bit quicker because the condensor is already cool but we are only talking maybe just seconds @ that.
The way I've seen cars with stock electric fans is that when the compressor is running the 2nd fan runs but when the compressor goes off so does the 2nd electric fan & the 1st fan will continue to run off of coolant temp.
This ends the A/C class for the night, gotta get ready for work.
