Re: EXPRESS 2500 AC Problem
Control head is a good place to start, I had a 2005 F-650 that took me two years to finally get it working right, tried everything under the hood, driver told me that it worked fine in the AM going out the the jobsite, but when it was hot outside later in the day, the A/C hardly worked. I finally decided that the control unit in the dash was the only thing I hadn't tried, so I ordered one, installed it the next day and problem solved!!

progress has little to do with speed, but lots to do with direction
