What you are referencing is probably the orifice tube + a screen.
There are many things that can change the air temperature inside the car.
1. Inside AC/HEATER duct under the dash, the temperature door can be open a bit and let the warm air mix with cold air temperature.
2.The purpose of the orifice tube, that is between the high pressure and low-pressure tube you can feel with your hands the cold and warm tube
The screen is blocking particles of metal from A/C compressor if the compressor is defect.

high-pressure side is HOT
low-pressure side is COLD
3. A/C compressor clutch could slip more than it should. The air gap has too much clearance.
The location of the orifice tube is :




New Orifice Tube EX 5151C 302272679 S10 Trailblazer Blazer DeVille eBay
To show you an example withdrawing and principle of A/C system and where to look for your question.

Hope it helps.

I think you might need a new voltmeter! The true voltage of a lead acid battery should be 13.5 volts. The alternator just fills the battery with AMPS. Its output is regulated at 13.5 volts. Put a 12 volt bulb on the battery and it would burn it out at 20 plus volts, plus all the bulbs in your vehicle and probably the ECM and the Radio.

The harmonic balancer has nothing to do with the charging system, it just makes the engine smoother and not vibrate.

Since this will take many pages of this website, I recommend you go to a car parts store or a public library for your answer.
At either place will be a set of books telling you the information you need.
The books at the library should cost nothing, the car parts store will sell them.
They are make and model specific.
Some names to look for are "Motor's", "Chilton's", or "Haynes".
God bless your efforts.

The headlight courtesy module is not timing out. The ABS light will not affect normal braking. It is not cost effective to repair and as old as your car is, I would just remove the ABS bulb from the dash.

You may need a professional to get this hood open, and it will likely need to be on a car lift. Try this if you are handy, try removing the driver side fender well liner for access to the latch.

There should be a flasher plugged into your fuse box of attached to two wires under your dash. REplace that and see if it is fixed.

You can't. Service the system, fix the leak which is the front AC compressor seal.
