Adding Rear Air to The Hoe

[Smasal]

So I have been posting here trying to solve my rear air problem. Finally someone stated the obvious and said “check to see if your motor is present for the rear air". Guess what he was right. Turns out the previous owner had replace the entire headliner with the intentions of adding rear air but sold it before he finished. I know rear air can be added and the condenser and the compressor are the same size whether you have rear air or not. The hard part is the laborious headliner which the last guy has already done ;-). And since GM pre-wires for rear air and I have already confirmed there is power to the wires, I figure why not? I have found the entire blower motor and duct work at a salvage yard for 200.00. This also includes the coolant lines. So my question is, is there anything I am not remembering?

1.Coolant lines run down the frame right?

2.I can just punch out the cap that is blocking the wholes for the lines right? In the back right wheel well?

3.Is it that easy for a pretty savvy car salesman who can change his own brakes, oil, differential and welded his own flowmaster exhaust on?

You're wlecome.

You should be able to pull it off if you can do those other things.

Note. Charge on a system with rear air is 4lbs vs the 2.8 for a system without.

So I copy you on adding more r134a. I am assuming I add it to the low side port engine running, front and rear ac on full blast?

Also am I right in assuming this is all that needs to be done is by the unit and plug and play right? Because in a tahoe with rear air the headliner itself is the duct work after the c pillar?

rear air project

did you complete the project? I'd love to hear about it as I would like to do the same to my 97 as the truck is hard to cool with front ac only down south.
thanks
