Multiple issues with 2004 Pontiac Grand Am, V6

Asked by Jun 08, 2014 at 10:04 PM about the 2004 Pontiac Grand Am

Question type: Maintenance & Repair

My Grand Am has started making a knocking noise in the last week when I turn on my AC.  I assume the compressor is going out but how can I be sure?  It still blows cold air (albeit only when I turn it up to max, a different problem?) but I don't want to wait on it to quit completely if it is going to do so I need to figure out how much it is going to cost to replace it.  Also, if I need to change the compressor how will it affect the rest of my AC system?  Meaning will I need a professional to adjust my cooling system if I have to change the compressor, or is this just a part swap?  Please advise, thank you.

If it is blowing cold ,and just starting to make the noise,you may need to go have it charged with a little ac oil,may save you from having to replace compressor.

To replace the compressor correctly you'll have to evacuate the refrigeration system, replace the compressor, orifice tube, and accumulator. Then vacuum, "sweep", and recharge the refrigeration system. HTH. -Jim
