Hi,
i charged the AC yesterday on my 1996 5.8 Econoline E-350, was really blowing cold in front, vent air was coming out at 44 degrees at times, but the rear left side panel in the rear was steaming hot with the rear fan on high, i can't find any controller that shifts the air up to the top rear vents, is there any switch that does that? i see nothing on the dash and didn't find any switch or control in the back either, seems like it was in defrost mode or something, please let me know, thanks,
