Sorry if I missed this topic - I think my AC drain is clogged/partially obstructed. Sometimes I see fluid draining after running the AC, but often I don't. No issues with water anywhere in the passenger side compartment, but I am getting the musty smell. I removed the right front tire and searched, including removing a heat shield next to the exhaust and still nothing that was visible. Does anyone know where this drain tube exits the underside of the vehicle, and/or is there any way I might be able to blow it out from the evaporator end? Of course I'm sure that would involve taking the front half of the truck apart! 2020 Silverado 2500. Thanks.
