Cabin Air Filter

Does the 2004 1500 Avalanche have cabin filters.

No... only on the first model year. But there is a Dorman kit to put one in.

Just to add a little info... I recommend adding the air filter kit, and here is why. When you cut the a/c box to add the filter kit you gain access to the evaporator. My evaporator was so full of leaves, mold, and gunk it was disgusting, created a smell when the A/C first kicked on and was certainly limiting performance and efficiency of the AC system. It was worth it just to clean the evaporator.

Here was my evaporator before cleaning, viewed via borescope.

How did you clean evaporator?

Bottle brush and a pump sprayer with soapy water in it. Then rinsed with clean water.

Bottle brush and a pump sprayer with hot soapy water in it. Then rinsed with clean water. You'll also want several large beach towels to soak up the mess.
