Where exactly is the draintube for the AC condensation&Is ther a cabin airfilter on 2004 Chevrolet Express 1500

Have looked in every place Ive been told it should be but cant find it. I cant find any diagrams or video showing me EXACTLY where the drain tube is located. Also wondering if theres a cabin air filter on the 04 Express van. Thanks in advance.

So I've been told many times but I've looked and felt everywhere and still can't locate it. Would you know where i might find a diagram or picture of its location? Thanks for the reply.
