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.

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.

Trunk reless relay ! Which year is right ? at the top is shows 1992 Buick . An it also has 2005 ? Which is it ?

Sounds like the linkage arms under the cowl are binding or frozen.....motor can't push them

Is it spark or fuel that quits?I would start with changing the crank sensor as they fail on this model.

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.

GM OBD Trouble Code 17

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.

Sounds like possible shorted diode(s) in alternator

My 1992 Buick century headlights were not working so I replaced the relay now when I turn the knew switch on it takes a minute to 5 min before lights turn on

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.

I have to ask? How long since a tune-up? Are there any applicable trouble codes? As far as spark at the spark plugs, check the ignition module. Check voltage to ignition module with key on, pink wire with black tracer. If no voltage, check fuse circuit, fuse 6--20amp in relay center. Not only check the fuse, check the fuse circuit for voltage. During cranking rpms, it is the ignition module that controls spark, but, it has to see rpm signal, which comes from crank sensor. At the moment, I can't be positive which component or exactly where the fault lies. To reply, click on comment link.
