2015 Silverado AC project

[wafon]

Hi im going to install the ac system on my truck, it doesnt come with ac from the dealer, thats why the climate control is the one, without the AC button. I already ordered the compressor (got it from a wrecked truck, same engine btw) and the climate control from another truck too (the manual one, not the automatic), and already installed in the console, the thing here is, do someone knows the wire diagram to connect the compressor to the electric system, so i can use the original controls with it.

 

If anyone already did this, i really appreciate the right directions, or, in the case, some guide to achieve my goal.

 

Thanks

You might want to find a shop that has done something like this as the factory items don't just plug and play. Also, you will need an evaporator core and condenser.

 

Are you positive the truck does NOT have AC? Looking at the parts catalog, I show no options for a heater box without AC for a 2015 Cheyenne pickup.

I've never seen a vehicle built after 1994 without A/C.

You are going to need a lot more than a compressor and a wiring diagram. You will need to install a condenser. A dryer that is compatible with the compressor and module. An A/C module with the evaporator and doors that are compatible and the control head that is compatible with that module. You need all the lines from the condenser that will accept the correct orifice tube. An ambient temperature sensor and harness that is compatible. If you have electric fans then you don't have an A/C fan which you will need. The ECM computer has to be compatible. The A/C and fans is controlled thru the ECM computer. And the body control module will have to be compatible. You might need some different mounting brackets. On some models if you don't have just an A/C belt you might have to change the water pump. That is due to the different routing configuration of the serpentine belt and the water pump runs in the opposite direction. So the impellers are opposite of what they should be. That is something that should become a habit when ever you change a water pump. ALWAYS compare the impellers to make sure they are facing the same direction. These are just a few thing that you are going need. Now that being said if you go thru with this project. And it don't work when you are finished. Do yo have someone that you can turn to for help in trying to fix it. I know I wouldn't want to touch it. I would have no idea what has been done what is missing. If all the wiring is correct etc. etc.

 

Any way the few things that I have posted is food for thought. Good Luck

You would probably be better off ordering an aftermarket system rather than trying to integrate a factory system into a late model vehicle. This reminds me of when I was looking to install a factory set of TriMode side steps on my 2016 Denali. By the time you bought all the man parts plus every electronic module etc that was affected and had the dealer reprogram them the cost was equivalent to just trading up to a new truck that already had it LOL. I would be searching for a company that makes and sells an aftermarket AC system.

^^^ I agree 100%.
