Cabin air filter DIY

[retodd7711]

I had problems with my heater/A.C. in my 2000 Silverado. Even with the fan on high there was barely any air coming out of the vents. I got a new cabin air filter ($15.99) and it came with instructions. I thought I would post them here in case someone has questions. It wasn't really difficult; 5 screws and about 15 minutes. I blew out the filter housing and air ducts while I had it open.

does it work better now

My dad's 02 started smelling foul whenever the A/C was on. We replaced these and the air is fresh again.

Great Post and good pictures!! I just had my truck in for service and they said that it didn't have a cabin filter. I knew better however. Mine is a smoker truck (previous owner) with 80K. Should prove interesting.

Thanks again!!!

I did the filter change today. I got my filter from Orielly's for ~$22. It was a Wix filter No. 24805 (which cross matches with Bosch P 3730). Easy task except for the 2nd from the left cover bolt. My total time was about 30". Next time it will be 5".

This is a very common thing to overlook - good post

i've just recently read this thread and this is a good post... ill share what i've read regarding cabin air filters from ezine articles...

These days, everyone is looking for better vehicle performance and a better personal health. These two things can be directly related within a vehicle with the cars air supply. People are concerned about the quality of the air that they breathe while driving their cars. It is now possible to protect not only your car, but yourself and also your passengers as well, by having clean cabin air filters.

The air that we breathe is full of airborne particles and these airborne particles can pass through your vehicle's ventilation system and into the passenger cabin. The airborne particles can include pollen, mold, and dust which can irritate you and your passengers, causing all too common and unpleasant allergy symptoms such as runny noses, sneezing and blocked nasal passages. Airborne particles can include smoke and fumes as well as odors. The air passing into your car comes through your vehicle's vents. These vents can become blocked and the airflow into your vehicle's passenger compartment will be reduced. If the vent filters are not regularly replaced and become blocked, your vehicle's heater and air conditioner may ultimately be damaged. Therefore, cabin air filters are a critical part of your vehicle's ventilation system.

Cabin air filters work to your benefit by removing airborne particles from the air that is flowing into your vehicle's passenger compartment. Because they improve the air quality inside of your car, they offer great relief to allergy sufferers and protect against from airborne pollutants. Clogged cabin air filters can cause fogging of your windshield due to improper vehicle ventilation. This can lead to dangerous driving conditions that may jeopardize your safety and the safety of others. Auto exhaust pollutants from fellow travelers in other vehicles can damage your health as they pass through your car's ventilation system and into your passenger compartment.

With cabin air filters, they offer protection on your vehicle, along with an additional health benefit by helping to screen out these toxic and harmful gasses, such as ozone and hydrocarbons compared to other air filter like Premium Guard Filters. Cabin air filters also help reduce the unpleasant odors from gaseous pollutants.

When I had my '99 I changed mine and the one on my uncle's '02. Definately made a difference... Mine was full of pine needles and seeds and everything else. There was one bolt that was really annoying trying to get back in on the kick panel. The work trucks ones are even easier since they don't have a kick panel.

damn, now i'm gonna have to replace mine. i doubt they have ever been serviced or changed

[droppedgmc]

I'm sure mine look like that...I can here crap blowing around in there. thanks for the reminder about these

[DirtyLarry]

I forget about those cabin filters. I prolly should check my two GMT800's to see if they need them. Thanks for the reminder!

[andrewmp6]

Can we have a sticky for this?

[C10-Driver]

Great info... I'm going to have to change mine.

[Sillyoldman]

Thanks for the reminder. I also need to change one out.

should be the same as 4.8/ 5.3

2003 and up trucks do not have them. There are some 03's that may have them due to using up old stock of air units.

[andrewmp6]

So why they start using them and stop like that?

[JohnC]

Probably getting a lot of complaints due to owners not changing them. Keith.Seymore would be a good person to ask. He was on the GM team with these trucks at the time they were rolling off the line. I'll pm him about it.

Cabin air filters are one of those items that come and go.

For example, on my current program (Chevy Volt and Opel Ampera) we do not have them released for domestic use but do have them released for export.

The downside for cabin air filters is (a) initial cost (b) a reduction in air flow and (c) proliferation of HVAC units in the assembly plant. If the program team is sensitive to any one of those areas, or warranty cost (as indicated in the first few posts of this thread) then the filter is an easy victim of a cost reduction initiative.

Thanks for the inside input Keith!
