ok looking at a couple auto parts stores it lists a cabin air filter for my 01 f250 yet no one can tell me where its located and I cant find it in the repair manual I have....

So can anyone tell me where it is and how to change it?

 

there is no cabin air filter in the 01. i dont think they came out with a cabin air filter till 08?

 

There is not one. It is a add on option that mounts in the cab under the glove box. I have never even seen one installed...

 

Thanks guys... I thought I was going crazy... well maybe I am... just not about this...
