A/c work on and off at high rpm and the highway
I drive a 07 Mack granite. The mechanic replaced the clutch fan, compressor,drier, and the inside/cab control panel. When I shift at high rpm or driving in the highway (higher rpm) , the a/c work on and off. Sometimes the compressor stop working for a few minutes. But after a few minutes it kick back on, but doesn't feel as cool as suppose too. It's only happens on highway (65 mph/ speed governor) and if you shift at higher rpm. Work just fine around town ( if I shift on lower rpm)and when it's stop. Also the fan doesn't blow as hard like other truck , even on max speed
Is this a worthwhile discussion?
