Frequently Asked Questions

What is the refrigerant distribution valve?

It controls the flow of refrigerant between the front and rear evaporators or between different zones in a multi-zone climate system.

Why is my A/C cooling unevenly?

With the distribution valve stuck or inoperative, refrigerant cannot be properly directed to all zones, causing uneven temperature distribution.

Is this the same as the expansion valve?

No. The expansion valve meters refrigerant into the evaporator. The distribution valve directs refrigerant flow between different areas of the vehicle.
