Peterbilt 330 | Poor A/C Performance
The customer came in because the A/C wasn't keeping the cab cool.
After a full inspection, we found the evaporator completely plugged with dirt and debris, restricting airflow through the HVAC system. Even if the A/C is producing cold air, a clogged evaporator can keep that air from ever reaching the cab effectively.
Our technicians removed the evaporator, cleaned out the blockage, restored proper airflow, and got this Peterbilt back to blowing cold.
