Where is the cab air filter located for a 1500 2007 Dodge crew cab?

While Quad cab is a style name used only by Dodge Ram, crew cab is used by Dodge and several other car manufacturers

The mass air flow sensor is located inside the air filter housing.

there should be a filter under the panel where the wipers are, also is all of your fan switch setting working?

there is a cab air filter located under your hood, pass. side under the wiper area, but this should not be the problem if your loosing coolant, check your heater core, if your fan only works on low. check your blower resistor you can pick em up new for around 20 bucks. hope this helps and god bless.

check under the hood in the wiper cowl, should be an access panel. if not check behind the glove box.

Your cabin filter is located on the passenger side. Open the passenger door and under the glove box you will when looking up you will see a panel to remove and slide the filter out. The filters are a little pricey, but if they are not flowing well they will affect the capacity of warm or cold air output.

Manual says your truck may,or may not have a cabin air filter, (optional equip) if u do have one it will be behind the glove box under the dash behind a compartment door.

hey jack open the back door and look up top where the hinges are and that should be the one for the back and the front if it is not up under the hood where the wipers are then check up under the dash

If you haven't figured it out yet, try the two links below. They have pics and diagrams. I haven't done this yet but, Nissan suggesting to have it done. (Sitting in the dealer having oil changed as we speak. They want $90 to replace the 2 filters.) I'm planning on doing it myself to save about $70. Doesn't look too difficult - just a little time. Parts are about $22 at local parts store. hope this helps. (Won't be back on this forum. So won't see any response you submit back).
