Does anyone know where I could purchase a new replacement seat cushion for my 07 Aspen. Mine is worn out from getting in and out.

 

Best thing to do is to first go to a Chrysler parts site like https://www.factorychryslerparts.com/ to find the part number. You will need to know the trim code. Then do a search for the part number to try and find it available online. However, based on a the few sites I checked for the seat cushion, it is no longer available. Meaning you will probably have to search at a junk yard to hopefully find one.
