Hi Guys. Trying to clean out the evaporator box some without removing box and evaporator. I blew air through the bottom and didn't help. I read somewhere that someone removed a clip and a couple of screws on the front edge of the evaporator box and was able to clean in there. I was thinking since the blower motor blow air on the evaporator that there might be an opening to spray a cleaner and water in there? Anyone tried this? Thx in advance. Nel
