What causes my car A/C to make a loud noise? The noise comes and goes. Can I get it fixed & for how much?
The possible reason why your car is making a loud noise could be that some parts in the engine are not receiving or some oil Dependant components are with low pressure. A professional mechanic should evaluate your car and give a solution. Get this and more information on http://www.ehow.com/facts_5554127_causes-loud-noise-engine-starts.html.
This has happened to mine too except mine squeals going down the highway,I was told $600-$800 for new unit plus $600 to install.The reason for the noise is that the seals are worn and lubrication is non-existent.
