Common Symptoms of Dodge Ram 2500 AC Condenser
Keeping the pickup truck's interior cool and comfy, especially during summer, is made possible with a fully functional air conditioning system. But, at times, the cooling system may go kaput, and you might need to replace the parts like the condenser or the evaporator. If you think your cooling system is already defective, then you had better perform some troubleshooting. Listed below are just some of the symptoms that will help you tell if your vehicle has a broken AC condenser as well as the reasons behind them.
Check for the compressor's clutch and examine if it is not turning. If it doesn't, then you should inspect the condenser, evaporator, compressor, and the hoses for signs of an oily residue. This oil is an indicator of leaking refrigerant in the car's cooling system. This leakage is usually a result of faulty seals and hoses. In other instances, the leaks are caused by pressure buildup. If this is the case, then you will notice that the system becomes warmer even if it cools initially. If you want to make diagnosis faster than usual, you may buy a refrigerant leak detector at your local auto supply store.
Unusual compressor noise
A defective AC condenser unit may manifest itself through a rattling noise. This grumbling noise is caused by an oil break down, which causes friction from bits of metal inside the AC unit. These metal bits, in turn, cause blockage to the condenser and result to an unusual AC compressor noise.
Clunking sounds from the AC unit may be attributed to a low system pressure caused by contaminants in the condenser. Sometimes, sludge or other contaminants may also block the lines, expansion valve, evaporator, or the orifice tube. This clunking sound occurs because of the vehicle's automatic shutoff feature, which results from a lower than normal pressure in the system.
A malfunctioning AC condenser unit may be caused by blown fuses. So don't forget to inspect the fuses under the dashboard panel for any signs of damage. Faulty fuses make the compressor inadequately lubricated because blown fuses disrupt the condenser's function to allow oil to lubricate the compressor.
