I was busy working on buddy's vette. I separated everything "A/C" from the all the harnesses, now just looking to clean it up. Separating
the entire harness as I did is NOT necessary, as there is not much to remove. However, I opted to do so in order to ensure that if anything
needed to be corrected to this deletion mod, I can easily find the entire harness, modify it as necessary, and retrace everything.
This will be the official thread where you guys can refer to on what you need to remove. I will clean up this post to make it a more proper
How-To once we get it all checked over and finalized. I'll also add more pics on where some of the components are later.
---------------------------------------------------------------------------------------------------------------------------------------
Here is a picture of the diagram. I need someone to confirm what they can. The bolded section below is what I really need help with.
The gray shaded is what I THINK we can remove, and still have functioning HVAC system for non-a/c air and heater.
---------------------------------------------------------------------------------------------------------------------------------------
THESE PARTS ARE RELATED TO THE FUNCTION OF THE A/C UNIT
A/C Amplifier (A17) - located on bottom left of diagram. This appears to actually control the A/C system when you push that magical A/C button.
This is connected directly to the button, if you follow it to the controls. It also goes to the engine bay parts, such as relays and compressor.
Therefore, this does not seem necessary to keep.
A/C Dual Pressure Switch - I believe this switch basically prevents the A/C from working if there is insufficient pressure in the refrigerant system.
Therfore, this is also not needed, and as you see is attached to the A/C amplifier.
A/C Thermistor - As the name implies, it's related to temperature of the current. This is basically an overcurrent protector for the A/C amplifier.
Again, not needed if removing the A/C amplifier.
A/C Condenser Fan Relay No 2 and No 3, Condenser Fan Motor, CDS Fan 30A fuse - As the name again implies, this is related to the condenser
and its fan operation. You can remove this.
A/C Magnetic Clutch Relay, A/C Magnetic Clutch and Compressor Sensor - These are related to the actualy compressor operation. If you've
removed the compressor, you obviously have no use for these.
10A A/C - This fuse is for the A/C Amplifier. You can remove this too.
--------------------------------------------------------------------------------------------------------------------------------------
THESE PARTS ARE RELATED TO THE AUTO FUNCTION (REGARDLESS OF WORKING/INTACT OR REMOVED A/C SYSTEM)
A/C Solar Sensor, A/C Room Temp Sensor, a/C Ambient Temp Sensor - I am not 100% on these. If my memory serves me right, when it is
set to the AUTO function, the unit basically determines if to use the Heater or AC, and determines how high or low the fan setting is. What I
am not sure about is if I set it to the AUTO setting with the temp to cool, then does the AC automatically kick on when it needs to, or do you
still have to push the AC button? I do not remember, as it has been a while since I've had A/C. I imagine the Auto function can still be useful
in cooler weather and winter, but useless in the summer without A/C. However, I am not too hung up on keeping the Auto function. So to make
things less complicated, I am contemplating on removing these anyway. However, if I remove these things, I am also concerned if the temperature
and fan settings will still work perfectly fine MANUALLY adjusted.
A/C water temp sensor - Located on the left portion of the Auto A/C Amplifier with a yellow and black wire going to it. I assume we need to
keep this. This is located in the heater core area, and is for the Auto A/C.

I know, long post, but any help and collaboration will be great.
These two pics are exactly the same, the first one is just smaller to make it easier for those with smaller monitors to view. Of course, you can always
right click and save to your computer too.
