Insufficient Cooling

The compressor is a scroll compressor that matches the air conditioning demand by changing the compressor stroke, instead of cycling the compressor clutch. A capacity control valve located in the compressor senses the low side pressure and causes the compressor to adjust to A/C cooling demands. The compressor always runs and the system does not cycle. However, the compressor may cycle if the cooling load is not reduced enough by the capacity control valve.

Preliminary Checks

^ Inspect the proper operation of the cooling fans.
^ Inspect for system voltage above 10.5 volts.
^ Inspect the A/C fuse. Replace as necessary.
^ Inspect the A/C blower operation. Repair as necessary.
^ Inspect the clutch coil electrical connection. Repair as necessary.
^ Inspect the drive belt. Replace if damaged or missing.
^ Inspect the condenser for restricted air flow. Clean as necessary.
