do the 01's have the in cab air filter? Smelling a little stale with the AC. Checked my manual but all it saids is "if equipped". I ve looked under the dash but dont really see anything.

yes, i changed mine in my 01 last spring. thers a panel under the passenger side dash that you need to drop, its held on with 3 or 4 screws that i believe are around 8mm. then you should see the skinny "door" to the filters, pop it open (first put something on the floor to catch debri, trust me) the first filter pulls straight down and the second one is tucked in towards the fire wall, you gotta pull it back to the opening then pull it down. reverse for installation.

Also they are a little pricey. :eek:But I feel they are worth it. I don't believe the later models have filters.

For those who need to change the cabin air filters 2000-2003 or 4? only. Obtain a 1/4" drive ratchet, small extension, 7mm and 5.5 mm sockets, small flashlight, and a vacuum with hose. Put some sort of temporary mat or bag on the passenger side floor to catch debris. Move the seat all the way back for under dash inspection and acess. The large black plastic dash under cover is secured by three 7mm screws along the front and hooks in the back. Only loosen the left most screw under the radio about 3-4 turns as it is nearly impossible to put back into place if removed. Remove the center and right screws and lay the sheild down still hanging on the left hand screw. On the now exposed HVAC box about half way between the door and center console you'll see a removable panel with 2- 5.5mm screws. It's about 2" wide and runs on the bottom from back to front then up the front about 4-5". Take the panel off and behind it are the filters. The first one is exposed and the 2nd is just above it. Wiggle them out taking note of their positions. Use a shop vac or similar to suck up all the dust and debris that will still be in the compartment and fall onto the sheild and floor. Install the new filters by sliding them into place making sure the foam applied to thier edges will seal against the walls of the box. Now just reinstall the covers.

With it done start the truck and kick on the A/C and be amazed at the difference. I'll never go more than 2 years between filters again.
