[DML] Re: Air Condition at Highway Speeds

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

You must verify that BOTH fans are working, especially when running
the A/C. If the refrigerent is NOT R-12 it becomes even more important
 (and harder) to get the system to cycle properly. There is supposed
to be a label indicating the conversion, the amount of refrigerent,
and the pressures if you no longer use R-12.
