It makes sense if the fan motor gets hot, that the vent line would allow hot air to escape. But, is it more of a drain vent ? After disassembling my burnt out fan i noticed that the entire back was sealed up pretty damn good, combination of resin and sealant, but water still managed to get in there , get under the terminal cap and corrode the terminal contact, and those were sealed as well. So, would it be wise to seal / RTV any seams , cracks or areas on the motor housing that water could get into to further waterproof it ??? except the breather tube of course ….Im racks deep everyweekend !!!
