There is a cabin filter for models up to 2007. The 2008 model should not have any.

If it does smell like mold by the way, replacing the filtew wouldn't be enough.
Mold is inside the ducts, and the smell will come back in few days even with new filter.

If you have bad smell coming from the A/C, then you need to decontaminate the evaporator.
This is done removing the cabin filter and spraying a good dose of Lysol or any similar anti mold and anti bacterial product inside the blower.

Regards.

Look for the cabin air filther in my 2000 gmc jimmy


I'm 99% sure it doesn't have a cabin air filter. I've serviced many Jimmys and similar GM trucks of the same era and never replaced a cabin air filter or seen a reference of one in manuals. What kind of smell are you experiencing? Is it a musty moldy smell or a horrid animal smell?

Is the fuel filter for the 2004 GMC Sierra 1500 crew cab in the gas tank?


You may be lucky and the fuel filter is still on the inside frame rail under the drivers door. 2004 was the change off year and 2005 was defiantly the no serviceable fuel filter.
You can go to the dealer with your vin number and they can look up in there system if you have the external fuel filter, or you can just look for it on the inside of your frame rail.
Thank you for using fixya and be safe.

Oxygen sensor[s],map sensor and fuel pressure regulator.Although you should have a check engine light "on" with any sensor malfunction.I would look at fuel lines for a leak under vehicle.

Where is the cabin filter on a sierra 2004 gmc sle crew cab truck


The 04 SIERRA is behind a panel with 4 screws under the glove box...Remove the screws and cover and slide it out.There is actually 2 in there and it is easy once the cover is off.

Usually there are extremely detailed instructions that come with the new filter when you open the box...Follow these instructions it shouldn't be too hard.

the small radiator just inside the cab, where the hoses go to the heater is leaking. You may try using stop leak (many don't recommend this) or take off the heater radiator. it will probably get worse when you turn on the heater and fog up the windshield if not fixed. hope this helps.
