What is the mating connector for the connector on Drier tube assembly (AP3135774, Manufacturer's Number 4387019)? What is this connector used for? The system is R134a yet this connector does not appear to be a R134A connection. Is this the low side charge port or place to check low Freon?
ANSWER Hello DJ. This is a repair for an HVAC Tech. The port is the high side, not the low side, and is used to monitor the high side of the sealed system.
