Car A-C Problems - Troubleshooting Auto Air Conditioning
Car A/C problems are one of the most misdiagnosed issues when it comes to automobile repairs. The number one question that auto technicians have to troubleshoot and find, is "why the Ac is Not blowing cold." When the car's air conditioner has this problem, it can be caused by one of many things. The most coarse cause of the air conditioning blowing warm air is a refrigerant leak. No matter if the Ac law uses R12, R134A or any other refrigerant; the law of carrying out is the same. They all need a full payment of refrigerant to work properly. Refrigerant can leak from any of the components in the system. A car's Ac components are placed in distinct areas in the vehicle - not all together in an literally replaceable unit like a house Ac "window unit." It is critical that the failed part is placed and replaced to insure a long chronic repair.

Look for unavoidable Signs of Leaks
The first thing that anyone can do, mechanic or not is look for an unavoidable sign of a refrigerant leak. Most systems will have Uv dye in the law which is neon yellowish green. It can be seen easier with a black light, but it can still be graphic to the naked eye also. If there is no dye in the system, the leak may trickle out clear oil. examine all of the components starting at the service ports. Look at the service fittings for leaks and all of the hoses. Succeed the lines each direction paying particularly close concentration to the metal ferrules that connect the rubber hoses to the metal lines. Check for any lines that may have made experience with other components under the hood and may have vibrated and caused a hole to be rubbed through. The condenser is placed in front of the radiator, check every quadrate inch for signs of impact damage that may have caused a leak. Even without a rock or something hitting the condenser, there could still be a leak - look for evidence of any oil residue especially on all four corners.
Detect a Hard to Find Leak - Troubleshooting
After a quick optical inspection for leaks of the components that are under the hood, it may be critical to look a minute supplementary with the help of a refrigerant leak detector to troubleshoot the problem. If the law has minute oil in it, there may not be much residue to see from a leak. With a freon leak detector, the leak can be detected even if it is a very slow one. Go over all of the components as mentioned before, but this time with the electronic leak detector. The evaporator is the component in the passenger compartment, which is Not graphic like the other components from under the hood. Leaks from the evaporator can sometimes be detected through the vents. A coarse place to detect an evaporator leak is from the evaporator drain. Refrigerant is heavier than air, so it will plainly go out the water drain for the evaporator. Be rigorous Not to allow water to enter the tip of the leak detector or it may be damaged.
