[daniagm]

I came back from the dealer with a cabin filter part #CF104 /52485513 A/C delco there are 2 filters in the box 10x5 1/2x 1 inch thick white filters, I thought that I read in the past that there is 1 filter and 1 screen can some one here give me some info.

                              Thank you

Yep, Ac Delco# C104, GM# 52485513, Fram# CF8791.  Two filters / box.  I believe Ryan has some pretty good pics on his website of this procedure.  The filters are sandwiched in that obnoxious box under the pass side dash.  Change'em two at a time.

once you pull one out there is another one inline towards the front of the truck,i changed mine at 50,000 miles when i wasn't getting any floor heat.

Passenger Compartment Air Filter Description

The filters are located in the heater and evaporator module in front of the evaporator core. The filters are accessed through a cover to the left of the blower motor in the heater and evaporator module. These filters are designed to filter:

 

Fresh air entering the vehicle.

Recirculated air within the vehicle.

In addition to filtering duct particles out of the air, the filters are also designed to filter out unwanted odors that may enter into the vehicle.

 

The filter assembly consists of two separate elements. Each of these filters are identical in appearance and operation. These filters are removed and installed one at a time through the access door. The filters may be bent slightly which will allow for easier removal and installation.

 

The filters have a 12 months or 20,000 km (15,000 miles) change interval. These filters may require frequent change intervals depending on driving conditions

I've never done mine.  I never even new they existed until a couple of months ago.  What is the cost of those bad boys?

AutoZone has some off brand for like $19.95. I havent changed mine yet (currently 12,000 miles) but I checked it about a month ago and they are pretty black. They even make my hands black when I handle them. Yes I do live in a pretty dusty area!

i bought mine from a local dealer for a grand total of 25 dollars. pricey, but after i changed them i noticed for the first yime that i have virtually no dust in my truck,quite clean. now my 87 chevy always has a fine layer of dust on the dash and intument cluster.so next time you get into your truck look around and you might be surprised at how clean your interior is compared to vehicles with no filters.kind of neat

Can someone please post a how-to on this?  My Chilton doesn't seem to cover this, or I don't know what title they hid it under.  Thanks.

Comment on those instructions ... You don't need to remove the screw holding the small air filter cover plate (really a hard plastic strap) ... the top of that strap can be easily unfastened/popped off with a flat blade screwdriver then after refreshing the filters it just pops back up in place.

Does anyone know if at least one of two filters can be a charcoal filter and is it even available?

Replacing these are easy...  I have Hastings in now.  The air flow is so much better.  Best 22 bucks i spent on the truck...

You can also get them through Amsoil. I paid $17 + s/h for mine and they are made by Hastings.  Now I just need to find the time to install them.

there is a charcoal filter that you can use 1 of with 1 regular filter. this is supposedly recommended for smokers or other strong odor problems. Not sure what the part number is or where to get them, but I know others posted somewhere that they installed them.

The charcoal pn (and a whole lot more) is on this site:
