Automotive Air Conditioning diagnosis
Diagnosing difficulties with an air training system can be quite complicated. This section will take care of some common issues linked to the A/C system. Constantly wear safety cups and gloves. Keep all loose fit garments and the body parts from going parts. For issues not covered below, a professional auto mechanic or specialist is consulted. Find a repair shop.
Cool But Not Cold
In the event that air-con is defined to max cool and followers on high, but is just blowing moderately cool air:
Look at the pressures in system using a manifold measure ready. The recommended high-side and low-side pressures are available in the repair manual.
Whenever diagnosing an ac issue, it is easiest to begin at compressor.
If there is no voltage - a cycling switch may be bad, a fuse is blown and the system might not have sufficient refrigerant pressure to trip the low stress cutoff switch that cycles the compressor.
Leaks would be the common problem linked to the air-con system.
If pressure is reduced, then there could be a leak.
