Reporting back after a week of use.... No issues thus far, AC still blows down into the 36-37 degree range. Liking that my truck handles the heat a little bit better than before and my AC seats really get frigid now. Happy Happy Happy!

where is the best place to get the parts needed to make this? Radio Shakes are closed everywhere in my area...

ANy electronics store would have what you need, resistors are dirt cheap....

Hell, if you can't find anyplace PM me your address.... I'll send you one pre-made. I have enough parts to make 11 more LOL.

Going to check my 15, it's not bad since we just tinted the windshield (rest of truck already done with ceramic) with ceramic tint which helps massively. I always do 70 so that it doesn't impact visibility just helps block all the heat.
Black truck, black interior in AZ = super duper hot.

I'll be interested in your results, the other group of people feel that the 2015+ has a PCM change that cycles the compressor more... making the AC cooler.

Hello, I placed a 470k and I am getting about 33 degree vent temp. I am confused do I need to increase my resistor to like 580k or lower it to being that temp up to around 40 degrees? Thank you.

What was your initial temps? You will need to add resistance to get the temp warmer, I wouldn't run it at 33 degrees personally.

Haha. This thread is awesome. Who says you need a dealer!

High 40s and would off cycle to mid 50s.
So every truck responds differantly to this, hence 1 size not fitting all... I would try adding resistance and seeing if it warms it 3-5 degrees or so. You may want to try an adjustable potentiometer to find your trucks sweet spot...

Hi everyone, Digitaltrucker here from F150. I wanted to explain one thing a little further. What you are doing here is adding resistance to the temperature probe that is inserted into the coil. By adding resistance, it tricks the system to thinking that the coil is warmer than what it is. Hence it cools longer.

For many, with poor performing ac systems, this work around lowers your vent temp and also tightens up your cycling points. Most with issues see their trucks cycling on the low side at 42 and high end at 46. This is way to long and will never cool your truck.

Please know that these systems were designed this way and it is believed they did to meet fuel standards. These poor performing systems are not low on freon!

On my personal truck, not the donor truck I reference in the post, the dealer replaced my coil because the probe, via IDS, was indicating a very wide cycling range. The only way to replace the probe, is to replace the coil. It had little to no effect on the system.

Another issue is this, the probe is suppose to cycle the system between 36-38 degrees, per Ford design. They dont.

This work around works very well and has made the hot Houston summer, very doable! Lower temps and humidity and it is getting close to removing for the winter.

My wife laughs at me, her edge freezes her out at she has to set it at 74!

What value resistor did you put in parallel with your temp probe?

Do you just jam the resistor in with the other wires? Does it matter which side the colored bands (on resistor) are in relation to the plug wires in the plug?

Jamming it in would the technical term... I prefer "shoving". LOL... Yes, just stick it in there. If you use a resister only it might fall out though, hence why I put the ends on... makes no difference what direction you install it.

Sorry to stir up an old thread... I was wondering if these resistors are 1/4 watt or 1/2 watt? I bought a 2013 Platinum Screw in February and didn't know the AC wasnt very cool when I bought it. Now that it's warmer... well, you know. Thanks in advance for any help.

Resistors are 1/4 watt..
