Some people have taken pcv pipe and fittings (T) fitting and made a vent. Im going to cut the hose about a foot away from my 45 degree elbow and put a (T) fitting in there with a peice of hose to make a vent cap. Have you tried the AC again? Helping people is what I do for a living. Im a customer service representative, boat and ATV instructor for Tracker Marine Boating Center here is Kansas City. I instruct people who to operate, maintain and take care of thier boats and ATV's. I take people to the lake and show them how to do everything when they purchase a new unit. I also deliver 4 wheelers to thier house and teach them how to operate it. Every day Im either in a boat or on a 4 wheeler. It all 4 wheelers now since the lakes here are frozen over. I have had 5 ATV go out this week. Sound like your exicted to keep working on the pup!! stay in touch and let me know how the AC goes as far as getting colder. this is the best forum Ihave ever been on.
