Q: Air conditioning out

asked by on

The air conditioning is not working.

By far, the most common cause of this is low refrigerant. If the refrigerant is low then this will occur. This happens over time as the refrigerant will slowly leak out. A mechanic would start by checking the pressures in the system. If it is empty then it has a major leak that must be diagnosed. If it is simply low then some refrigerant would be added. If the system is full then there is an electrical issue. The most common electrical issues on this van are either a failing compressor clutch relay that needs to be replaced or the clutch itself. A voltage meter would be used to diagnose this.
