1997 Bravada A/C condensate drain

1 of 2 ways, if you have room to get under the truck were the firewall is on the passenger side you will see the drain on the black fiberglass plenum, use a can of keyboard air and the extension, and blast a few shots into it, or use a piece of wire and run it into the hole just enough to clear it. Or pee the rug back on the passenger side and find the plastic tube, drill a small hole and run wire towards the bottom of the truck. Then plug the hole with silicone.
