My evaporator canister did not have any carbon chips in it anymore, I could see the carbon chips under the battery tray where they had come out. The canister had a filter at the bottom that was worn out. I took the valve apart on the top,Just pop the top off. I rinsed the canister out with the water hose and blew air through the passages. I put the valve back together and put vacuum on it and it held vacuum. I went to Walmart and bought activated carbon chips in the pet supply dept. Next to it was a filter I got to make my bottom filter. I cut the filter apart and used the plastic screen to help keep the chips in and help hold the filter. I put in all of the nine oz of chips.
