The ac condenser is behind the driverside rear tires. It is cooled by electric fans that blow out. I took the grill off so I could get in and clean it up or at least wash the coils. In getting ready to put the grill back on it appears to have been mounted wrong. The fins are mounted "/" which would force more air into the condenser as you are driving down the road, thereby fighting with the electric fans. It is my thought that the fins should be mounted "\" to help draw the air out. So I think they should be mounted to suck out, not blow in.

So could some of you check your coaches and see how yours are mounted.

My fans pull outside air into the condenser; the grille fins are "/", correct for forcing air into the condenser when moving.

Now it means double checking rotations and then checking the wiring. Maybe the fans are running backward. That would explain low air movement.

A DC motor will spin in the opposite direction if you reverse the polarity - this is how an electric motor makes a door window go up and down
