Kyle - I'm determined to get Auto Climate Control in my 2015 Silverado I just picked up.   Thanks for the detail on how you were able to accomplish this.  I have everything on order now, down to the molex connectors that are needed in your description above.  What I cannot find is the wiring diagram of the X1/X2/X3/X4 connectors into the Control Module.   Can you please let me know where you found that so I can grab it .   BTW, my new control module 13591693 has J1,J2,J3,J4 not the X....   I assume your had it as well?  And the driver upper and lower duct temp sensors - where did you mount them?  

 

You have to find them in the upfitter electrical wiring manual which is free online, the J should correspond to the X fittings, they will just be listed as X in the manual. If you give me some time I can try and find the specific wiring diagrams related to the connectors.

 

Not sure if this link will work, but this is it:

Hello Kyle,

I am interested in the HVAC mod for my 2017 WT Double Cab (midnight edition).

The truck has the light sensor in the dashboard. Would I need the additional sensor?

Will it mount along side of the existing sensor? Also I have purchased the HVAC control

for a 2017 High Country  #84173748 w/ATC. I installed it and it has full "manual function" with

the exception of the last blower Icon being active on the IOB 7" screen. It looks like the Dash Sensor

and Temp sensor are the same Part Numbers as your install. The ATC Module I am purchasing is part number

84237325 also for a 2017 High Country with ATC. Would you be willing to assemble the required plug ends and terminal

wire harness for me. I have trouble with the crimping operation due to nerve damage in my hands. I will of course pay

 for everything and your time. I have successfully installed the "Heated Wheel" upgrade along with Pgambola wire harness.

My next mod after the HVAC ATC will be the conversion from my "IOB" 7" infotainment center to the "Denali Cluster". It looks like

I'll have to replace the entire HDMI, Screen, Radio etc to realize the Denali upgrade. 

Also are there specific markings for the temp sensor for the ducting such as a circle or molding mark for install?

Thank you for any assistance and information you are willing to share.

Love your engine mods on your truck and your vids. I sadly have the lowly 4.3L in my truck that will stay stock.

First off want to say thank you for all this way to knock it out of the park. I have a 17 Silverado are the part numbers the same? I know gm likes to use the same modules for what seams to be decades but when I'm looking up the part numbers I see that they seam to end at 15 for year range

      2 speed transfer case optional now?

      I thought I was building a HD 3500 srw, maybe I was lost.

      Which 2027 engine will you choose?

      No doubt, I definitely agree with you. However, considering the 6.2 and 3.0 have been catastrophically failing with very little miles, I figured I would put trouble free. I’m at 18,4xx and still not a single issue.

      It’s never dry here but it gets hot. My 4 vehicles I keep at home drive an 18 mile loop. One 6 days a week. Two about 3 days each and one once a month. Only one goes on trips about 4 times a year 1000 to 2000 miles each time. One 26 years old gets driven once a month for 22 years. One 14 years old goes 6 days a week. The other two are recent at 2 and 4 years. All are performing normal no extra service other than that would be half of recommended or severe service in the maintenance manual. No extra water or steam out the exhaust or premature plug wear. I would consider an 18 mile loop would be enough. So apparently once a month at 18 miles for 22 years has kept the collector car running well. About 45 minutes a month.

      Transmission Temperature Hitting 220s

      By newdude · Posted

      It is working as designed.  NHT and non NHT trucks have the same exact transmission cooling setup.  NHT just gets a larger radiator.     The transmission cooler loop on these is as follows.     -Transmission out goes into an oil to water heat exchanger (item #1 in the first illustration below).  This exchanger has engine coolant opposite the transmission fluid and uses engine coolant to warm and then regulate the transmission fluid temperature when its in the operating window.   - From the cooler it goes to a thermal bypass valve (item #11 in the 2nd illustration below).  If the ATF has not reached the temp to open the bypass (194F), it loops back.   - When it reaches 194F, the thermostat opens and ATF then flows out to the oil to air auxiliary cooler (item #17 in the 2nd illustration) at the front of the truck.  From there it goes back to the transmission.     Your only fix would be to swap for the PPE thermal bypass delete block which will open the loop to the aux cooler all the time.  It will STILL run warm, probably 170-200F, but that's as low as you'll get it as its still flowing through the oil to water exchanger.

      Most say the oil temperature needs to above the boiling point of water to rid it of moisture and long enough to dry it. Many think that is about a hour at 212 F or more. Those people have never line dried cloths in a Midwest winter. Leave a pan of water sitting on the counter and eventually it all evaporates. So heat drives the time it takes. Water in oil under 175 F, the Nitration initiation temperature, is a minimum then for temperature and samples I've done that use Karl Fisher method say about a hour (in a healthy well tuned motor) over 175 F will dry it to under 800 ppm. Low enough to not be much of a factor. Motors with weak rings will take longer and the colder the air temperature the longer it takes.   On a cold motor there is also the condensation temperature. Blowby gases that contain moisture are subject to that cold cylinder wall, like sweat on a glass of ice tea. But also subject to the Law of Partial Pressures. Wear studies by GM and the DOD  indicate wear is a real issue below 85 F and a concern to 140 F but doesn't become a minimal factor until about 160 F. You know this intuitively when you see water vapor exit the exhaust pipe until the system gets above the dew point. It isn't magic, it's physics and it fascinates me. I know you didn't ask but....I over share sometimes. 😉    You keep the Camaro's high and tight.
