I brought in a Ford FISO to have my AC looked at. I previously had my truck worked on at another repair facility. They installed a part hose dryer filter combo for 650.00 and they said that I needed more parts a control module for an additional 300 dollars. I told them no I will bring it to someone that knows what they are doing. Scotty's diagnosed the problem as a $20.00 cycling switch. They repaired it right away and saved me a lot of money!
