Found the p/s inner most vent hole foam seal was crap. The outer cover, when pried off, seal was crap. The screen cover below it had the spongy foam seal and was wet. You can see the blower motor wheel in pic. Cleaned it all completely. The outer perimeter of the outer vent with the cover, got a good cleaning and sealed with fresh silicone sealant around the whole perimeter. The cover was completely cleaned and sealed and when I pushed it back in place, the extra sealer oozed out and sealed smoothly around the outer perimeter. The inner most vent hole was cleaned and new foam seal installed. The bottom of the cowling cover was completely cleaned so that it would lay against that foam seal. Reinstalled everything. Waited 1 hour for sealer to set up. Pulled the blower resistor. Ran the water hose for 20 minutes and watched and felt for water back at the resistor mount hole. Felt dry and saw no water drips. Almost forgot, did check the ends of the lower rails and there was no blockage. You can see one, in the first pic is torn on the p/s.
